After two months of investment, the amount that you have earned in Bitcoin is still good compared to earning nothing when kept in a wallet. I think if you keep it there for a year the BTC profit should look good.
Investing in bitcoin is always good as the price rise up many times. So investing with bitcoin in gambling is always good I know it is risky but its a chance to make your bitcoin double as well.so we should invest bitcoin in sites only real ones. I would suggest keeping all the bitcoins in hardware wallets for the year so the price will be triple as compared to the current price.
You can't double your bitcoins from investing your bitcoin in casino bankroll, hardly you will get 7% a year if the site is in extremely profitable situation.Holding the bitcoin in long term is profitable but multiplying them while holding is a smart option though but understand any kind of investment are risky.
