It is a good investment as long as it is not a shitcoin or memecoin. If that particular crypto has a real project then there is nothing wrong investing to those coins. A crypto can soar more than 500% of its price after some years as long as its development is continuous. If we invested to those coins in their early stage, it could bring us a huge amount of money that could be enough to use in our retirement. Been into crypto since 2016, price is really volatile but investing to it for long term is really a good choice for me.
Yes, I agree that cryptocurrency is a good investment but have a high risk also, you maybe win big and lose big. But still it is a great investment if you know how to run this and what is the process to gain a high profit. But, just like how other people define cryptocurrency as investment, some of them says it was good and the best place for investment but some of them says its not because there is a possibility that you might lose such a big amount of money in this. Investing in cryptocurrency might be hard since you need to research a good coins where you can earn a high profit but you should be aware with the risk. Don't invest something if you don't really know what to do.
