+500 USDT in spot wallet, using only 10% on future's wallet and every trade with only the 10% of that. Meaning 500 $ Capital, 50 $ on future to get margen and only using 5$ each trade.
Bigger the wallet - bigger the trade
Smaller the wallet - smaller the trade
Don't try to convert 10$ in 1000$ in day, you'll end up losing everything, go small, take profits and repeat every single day.
If you start with 100$ and earn 3-5% each day then you'll have 130 $ in 10 Days -> 170 in 20 Days -> +220 $ in the first month. Each month your wallet will grow and so your earnings!!
Constancy can make you a winner, don't lose yourself in a red trade, call it a day if you lose, start with a fresh mind tomorrow.
Don't be greedy on future, play safe!
