Same with me , when it comes to crypto-currency I trade only Btc cause it seems to be the only one that follows the market structure for now . Dont thnk Btc is hard to trade if one is very good at technical analysis, unlike other altcoins where most of my losses are from them so I've decided to trade Bitcoin only. The other altcoins are more tradeable using indicators so people good at using indicators made lots of profits from them but for pure technical traders it doesn't seem that easy at all.
I recently found out about Binance copy-trading. Don't know much about it for now but it seems to be a normal copy trading process, just like the other platforms offering similar services. I hope we will have something unique about the one on Binance that will distinguish it from the other copy trading platforms.
Both are profitable and risky at the same time, although crypto pairs are much simpler to trade Forex has more movement and volatility making it fast to to take profit or vise versa, while crypto takes a long period of time to go in any direction. One just has to pick the one that suit him best considering which one brings in more profits and less looses.
You can buy some of the top altcoins on the coinmarketcap; they usually perform very well during the bull run season. You can also try holding some gaming altcoins such as Sandbox, Vulcan and many others. Just make sure to make some researches on any project you are going to invest and also dont invest what you cannot afford to lose.
Just do an excellent research and find a good project to invest in. Not all projects are good these days only a few are worth investing in. Make sure to choose the best ones among them.
