I don't think taking loan to invest in cryptocurrency. Trading in general is a risky game so there is no point to advice someone to take loan for crypto investment, it's a rule not to invest the amount you can't avoid to loose, and loaned money will not give proper mindset. Cryptocurrency market is not really predictable, so taking loan to trade is not a good advice.
I once tried to borrow money from a bank as investment capital in crypto, but it didn't meet my expectations. The price of the coins I bought
keeps dropping, while I have to pay my loan installments regularly every month. Finally I experienced financial problems, because the money
to buy daily needs I had to use to pay off debts. Like you said the crypto market is very difficult to predict, so it's not a good idea to borrow money
to invest in crypto. It's better if we invest with small capital, but from the extra money we have, so in the future there will be no financial problems
if the market does not match our expectations.
That's the risk of borrowing money for investment if it doesn't match expectations, and having to pay according to the agreement is very uncomfortable if our finances are not good.
Never risk certainty with uncertainty, because investment is uncertainty that does not necessarily match expectations, it would be better if you borrow money for urgent or very important purposes such as for treatment due to illness or other.
Invest according to your ability even in small amounts, do not force what is not in accordance with the circumstances, borrow money for investment because you will face two risks, loss if your investment fails and still repay your loan under any circumstances.
Fortunately I have learned a lot from my previous mistakes by using money loans for investments. Now I only invest according to the finances
I have, indeed the profit generated is not that big, but it is safe to do. Unfortunately many people often risk certainty with uncertainty, simply
because of the greed that is in them. Eventually people who cannot control their greed will end badly, they will experience financial problems.
Don't be easily tempted to see the big profits shown by people who do have large capital, because everyone has different financial abilities,
we don't need to chase people who have stronger financial abilities than us. Therefore it is very important to be grateful no matter how much profit
we make, even though our capital is small and our profit is also small, but with proper financial management, we can get a big profit if the profit
we make is accumulated.
