It is better to invest in crypto currency and do it with your own money and not with a loan from someone.Investing in any coin is not only profitable but also has the possibility of loss. So those who borrow from others or borrow from banks to invest in crypto, I think they are making a mistake because they will face a lot of problems if the price of their invested tokens goes down.
For altcoins, please adjust it to the times, if the tide is very volatile, the advice is to watch and monitor prices, otherwise the potential for returning the money we borrow from other people will not be realized. The slightest dump of BTC altcoins is quite fast enough to press downwards and the rise is also very slow and forget to use the SL method if you have time even though corrections are a normal thing in the market cycle, every trader or investor will buy and sell until they are liquid or take their profits.
