It will be highly risky to use your life savings or take loan from the bank to invest on crypto especially alts coins, but if you all in btc, it is risky as well but if you are patient enough it is worth it, if i had invested my life savings in btc alone in 4-5 years back, i would be singing a different song by now
Compounding interest is a sure thing though and it's going to hurt, I would never take a loan to invest in crypto, I can already barely stand the huge swings, imagine if you're borrowing the money, heart attack city.
The longer the time period to repay the loan, the higher interest to be paid in accordance with the initial agreement. Of course, taking a loan is a very risky thing, especially using that money to invest in crypto, which is not certain that we will get profit quickly. This will make it hard for us to repay loans because of this pressure.
That is why it is not advisable to get loan to invest in bitcoin, for me, I save up portion of my salary to invest in bitcoin little by little though we can trust bitcoin our savings but it may take sometime, the profit is not instant, it may take months or even year to get profits because the price is very unpredictable and if you get loan the interest loans is becoming bigger the longer you pay them. This will only make your life hard because you will worry how to pay your loan and at the same time worry about the price.
