Assuming I can gather 500$ a week from here and there,how much exactly should I invest.
I'm not that greedy and there is no time constraint.
If you just starting to invest then try to invest small money and get some returns. This technology is the latest and will be future.
Instead of trader you keep your funds in bitcoins and altcoin in your wallets. I will not suggest you to invest the whole money becuase it basically works if you understand them.
Investments is a good decision especially in cryptos.
