Trading is a lifetime skill that is always beneficial if you know what you are doing, the biggest mistake of traders is trading alt that most times doesn't obey market structure,
when it comes to cryptocurrency, trade only Bitcoin.
Bitcoin doesn't just give you profit, it gives you security, it obeys market structure, for the past 2yrs I have been trading, I only have losess only when I trading Alt, price action trading I utilize will trading always gives me result when trading Bitcoin, but when it comes to Alt I really do feel as if am gambling, so my fellow traders, trade only Bitcoin, I don't know if anyone feel the same way?
Bitcoin is known to have attained a greater level of stability when compared to other coins, which has been the reason it possibly obeys the trends and even follows the pattern of price action. Most altcoins may not have attained this level of stability and are definitely not been able to follow up with price action pattern due to their too many inconsistency.
But then this does not rules out profitablity on altcoins trading, there are people who have studied certain altcoins so well they understand their patterns and they trade them and are profitable in it, but then generally trading cryptocurrency is risky and full of some many uncertainties. It's best you pick that which suits your style , study further and stick to it, with time you will definitely turn out profitable in trading.
