By number 2, do you mean forex? Ain't that much harder compared to ordinary trading with cryptos and stocks? I mean i can say that i have few to little amount of knowledge when it comes to stocks and cryptonbut not forex...
Although i agree to divide everything into three. It's truly wise to gain little by little instead of going all out, that's a huge gamble.
By No 2, i mean to trade with fiat currency in crypto pairs like USD or USDT, here we have many pairs is Tether market like ADA, NEO, TRX, SC, DASH, MONERO, LTC , ETH AND MORE ..you can trade with this pairs which can give you a good returns in your investment. $200-$500(daily) i must say not bad with $5000.
