Actually in the crypto world people have their own way of getting profits, one of which is as you mentioned Trading.

Your next question, you don't want to trade but you have some crypto besides Bitcoin and the core is profit, of course the benefits you can get by making long-term 'investments', you need patience in this case.

I remember my friend who was successful this year, he didn't trade but he made a long term investment in one of the coins (AAVE), In 2020 my friend bought Aave coins for $25 in 2020, at that time he only bought about 150 coins and he only needed to be patient for one year, right in May 2021 the price of AAVE coins jumped at $666 per coin.

From what I'm telling you, it can be an example and something you can do, the bottom line: you have to really choose the crypto you want to invest in, both in terms of market, demand, development etc., it is really you understand the best crypto.

Remember: the wrong choice of crypto you can be disappointed, right in the choice of crypto you can smile.
