  • I appreciate your👆effort and help over me and my family you've been there through have time you made us financially stable

  • Talking about stocks, Forex and cryptocurrency trading is the most profitable venture I ever invested in, I reached my goal of $120k monthly trade eanings. Wondering if viewers here are familiar with Mrs josie wallace FX trading strategy.?

  • When it comes to the world of investing, most people don't know where to start. Fortunately, great investors of the past and present can provide us with guidance.

  • [Great video really. Also i agree with your opinion, For the newbie if you are actually trading in the crypto space and you don't have a sound mentor. Then you are certainly going to get liquidated in 90% of your trades. Yeah that's the sad truth. For a start you need a good and experienced hand to guide you. Trust me, trading isn't difficult as we see it. With the right Signals and guide, you can earn hugely monthly.

  • who is the presenter on this tutorial?

  • HELLO, I'M NEW TO CRYPTO AND FOREX TRADING AND I HAVE BEEN MAKING HUGE LOSES TRADING ON MY OWN BUT RECENTLY I SEE A LOT OF PEOPLE EARNING FROM IT. CAN SOMEONE PLEASE GIVE ME A NEW STRATEGY OR AT LEAST TELL ME WHAT I'M DOING WRONG?

  • I totally agree with what you are saying…..<The fact is, BTC is the future of crypto and the questions traders ask themselves now if this is right time to invest? before jumping into conclusion i think you should take a look at things first. for the past few days the price of Btc has been fluctuating which means the market is currently unstable and you cant tell if it is going bearish or bullish. while others still continue to trade without the fear of making lose, others are being patient. it all depends on the pattern with which you trade and also the source of your signals. But all thanks to Fred Austin for his amazing skills for helping me to earn 19 Btc through trading chart. I believe we are in the spring phase. You can reach Austin on ͲeIєɠɾαm👉austiinfredtrade.

  • 🌈INVESTMENT IN FOREX MARKET ANALYST IS VERY UNIQUE IN TERMS OF EARNING.

  • Please I need someone to help me trade or invest the forex or crypto market because I’m tired of trading in losses myself. I’ve blown my account twice and it’s frustrating…

  • Although Screens across global markets <have turned red again, as market sentiment shifts back towards risk aversion, due to the worsening situation in Ukraine. While the start to the day was rather shaky, there had been hopes that equities might continue to push higher even with the difficult backdrop of the war in Ukraine. But those hopes have evaporated. Previously strong sectors such as banking are beginning to feel the pressure as investors reassess the outlook both for global GDP and tighter monetary policy, the latter exemplified by a pushing back of expectations around the first European Central Bank rate hike. European markets continue to be the most affected, from a combination of closeness to Russia (both geographically and economically) and by the weaker earnings outlook here compared to the US. Kremlin pronouncements have become more strident today, further reducing the attractiveness of the continent’s equities. This is the worst possible time in history to invest as so many don't back up their crypto assets. More emphasis should be put into day trading as it is less affected by the unpredictable nature of the market. I have made over 13 btc with 2.1 btc from day trading with Kristina A McFadyen's Signal in few weeks, this is one of the best medium to backup your assets incase it goes bearish.Kristina can be reached on ͲeIєɠɾαm👉Kristinafadyen.

Already making over 85% profit from my current investment and Trading with an expert is the best strategy for newbies and busy investors who have little or no time to monitor trade that is why i have made huge profits on my investment since I started trading with Mrs Evelyn Richard, her trading strategies are top notch coupled with the little commission she charges on her trade!

  • Hello, I'm new to forex and bitcoin/ethereum trade and I have been mrecentlyaking huge losses but I see a lot of people earning from it. Can someone please tell me what i'm doing wrong

  • The market is very unstable and you can not tell If it's going bearish or bullish. I advise y'all to forget predictions and start making a good profit now because future valuations are all speculations and guesses. When these reports are bullish take some off to the side lines, when news gets bearish start buying. "Keep it simple simple" that bear/ correction was the best thing that happened me. <But all thanks to ALEX VALENTINE for his amazing skills for helping me to earn 19 Btc through trading chart. I believe we are in the spring phase.
