4) Do not loan funds for investing in crypto
Avoid trading in cryptocurrencies with borrowed funds. It is a popular advice in the crypto industry that you invest only what you are prepared to lose. This means taking loans from sharks or banks is not advisable as you are risking your borrowed capital in a volatile market with no guaranteed returns.
i think that is really a dangerous act to take loans for the sake of investment in crypto because nobody know the up and down in the market, and that become terrible when the money of loan come down in crypto. I know a person who took a big loan for crypto investment but unfortunately he lost more than half of that money and then he was unable to return the money to owner. So i suggest to trade with your own money.
