Honestly, in trading i'm pure gamble. I have zero experience in analysis and sometimes only ask my friend what coin that he bought or maybe do future trading in which coin. Coins that i bought myself usually only BTC, ETH, or BNB which i will hold for longer time and sell when get a little profit.
You shouldn't do futures trading if you still don't understand it. I think the idea of asking which coin your friend have bought is a good start for new traders.
But as time passes, you'll have your own reference and you're going to learn from your own experience which shall make you rely on your own experience. And those coins that you've bought, they're all good to me.
