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.
Investing in hyips is always risky and its a way to loose your bitcoins rahter than to grow because they are all scams.Yes trading is good but firstly experience is needed and ready to loose some small amount at the start,but once settled in it,then yes it can be a good way to grow your bitcoins.
