I am considering taking a loan to buy btc and eth, is it a good idea? Because btc and eth always go up in long term. They never die. There seems to be a great chance of getting huge profit instead of losing money. A few years ago somebody in this forum asked others the same question and everyone told him not to do that, look at the price now. If that guy did, he would have been rich now. Nowadays the situation is not different, the price will continue to go up. I think people who invest more will earn more profit eventually. What do you think?
You have a positive attitude and you seem quite optimistic which is good in most cases but we are all talking about Crypto. This is a world full risks.
I do not recommend taking a loan to make a few dollars more. Yes, there is profit in cryptocurrencies, with Bitcoin and Ethereum usually climbing, but they go up and they go down. If the risk factor was low then my recommendation would be to go ahead blindfolded.
Best option would be for you to work a few months hard, make a $2k-$3k and then invest from there. Whatever profit you make from there, use that to invest in other coins and leave your initial investment there untouched.
