Well you can earn 5% interest daily on your bitcoins I think by doing some things. The first and not the recommended one is gambling. You can just bet until you got 5% earnings from your starting balance but it is risky. The other thing you can do is altcoin trading. This method will not guarantee a 5% daily interest but you'll surely earn here man im sure.
You cannot earn 5% of your bitcoin buy just doing nothing and there is no risk free to get your goal, you need to risk and I agree that trading is the best way to make that happen, however, do not just do trading if you do not have the basic knowledge and skills to make that succeed.
I Guess for trading altcoin and can make earn 5%~ not realy, There looking gambling for trading altcoin, still suru not realy you can earn 5%~ or than.
