For me it is better to save money because if you are going to save a lot of money for sure you are going to have a purpose to invest.
But if you are going to invest money and you don't have savings then that is going to be a problem after all.
Because you don't have back up funds for your investment if ever it is going to fall.
yeah, saving is the best for me either, in my opinion by doing that i get a possibility to make some good money without doing anything
But for me , i would like to invest my bitcoin into trading altcoin and keep it the rest. Maybe i will deposited 10 - 30 % from my balances in my wallet to trading and the rest would be hold it for the future .
