Futures trading is indeed profitable, but a crypto beginner should not venture into it in a hurry. I have lost money before in futures trading, but I have not done so since then.
Have you get profit from futures trading?
I don't request you to show proof of your Futures trading profit because it is your personal information and privacy, I respect it. If did not get profit from Futures trading, please don't say it is a type of profitable trading.
It is one of most risky trading types and should avoid by newbies and all traders.
Unless a newbie is practising regularly with demo, as you mentioned, he or she should not hastily start future trading. Few CEX I used don't have demo accounts, but on radar they only sometimes give trial funds to practice futures trading. If you utilize the trial funds and make a profit, then the profit is yours.
Trading with demo and real account are very different. You can not succeed in real account trading just because your demo trading stats look good.
Trading with small capital is easily as it contains very little pressure. If I trade with $100 and lose it, I won't lose my life.
Trading with big capital or bet all my asset, my life in trading is very high pressure and stressful. If I sold my house, use all money to trade and lose with my trades, I will lose my life.
Emotional impact would be small with small capital and would be big with big capital.
