I have been learning how to trade btc and altcoins by myself and having my experiences. I read online articles on trading signals and what to watch out for. I've made some profits and lost a good deal. Good thing I started with very little capital. Right now everything looks so negative especially as btc went so bearish.
I need advice on how to improve my trading because I really want to do this

Bitcoin is bearish up to this point. But it is not a problem. Because bitcoin will always go up. What you need to do in improving your trading is just hodl your bitcoin until you make awesome profits.
Probably, study more the market history. You might know that hodling is the key in cryptocurrency.
