even i say it is a big mistake to take out a loan to trade. there are many aspects that must be learned in trading, one of which is patience waiting to take a profit, if the money we use is from a loan of course there are limits and panic occurs in trading so many things appear that we don't want. one mistake due to panic in trading will continue to bring up the next error.

Yes you can trade when you have enough experience and good tip to choose the best coin.
