I would suggest that you continue on trading. For me it is the most safe way to grow bitcoin rather than investing it at hyips because most of them are scam but not all, others will last for month but will be eventually become a scam. Or gambling it because we all know that no one gets rich from gambling.
you are right that trading is the best way to grow up your bitcoin and i think trading is good than other investment and you can get a big profit from trading quickly and you can grow up your bitcoin quickly through trading.
