I will add to the previous post that this kind of investments are risky, hence you should invest only money you afford to lose or have locked in the investment for long time.

In my experience with Bitcoin, while the price did recover sooner or later, there were long periods the price was low and the news were depressing; I expect many did sell in such times and if you are one of those getting easily scared by that you better not invest. Even more, investing in bitcoin makes sense only if you plan to leave your coins untouched for 3, 4 or even 5 years, at least. Of course, financial emergencies tend to occur when Bitcoin price is also far from great. So you have to have a good plan.

Adding to this the risks the previous post wrote, it's not easy to invest into Bitcoin.

Now... you wrote "crypto". Many Bitcoiners will say that you may want to invest in whatever altcoin. Altcoins are way more risky than Bitcoin and I don't have a good rule for them to see profit. In my experience altcoin investments are a losing scenario on long term. Maybe on short or medium term some got nice profits, but I don't recommend altcoins at all.

So, altcoins are a no, and Bitcoin is also something that must be weighted carefully. Then you decide for yourself whether you should invest or not. Good luck!
