Even if someone is not an expert in technical analysis, he/she can trade and earn some money from it. By chance, I mean. So, trading should be treated as gambling in that case. So, don't put at risk a bigger amount than you can afford to lose and trade how much you want. Enjoy the process, learn something from it, but don't try to make money with it because you can end up with losing a lot because of your high stakes. Accumulating Bitcoin, on the other hand, never hurts.
Trading is risky but everyone can have profit or loss with some trades. Difference between an amateur and a professional trader is in long term of trading. An amateur trader who relies completely on luck factor can not get profit in the long term. The professional trader can get positive net profit in long term of trading because he is very knowledgeable, experienced and disciplined with entry and exit.
Amateur or professional trader, the vital thing to do with trading is to use Stop Loss order or Stop Limit order, to avoid terrible uncontrollable loss with market crash.
