It seems like there are several ideas that cross people's minds when it come to investing into anything and it's:

-I'm too late, it's already topped out and too expensive.
-I'm scared that it will drop when I buy it.
-I don't know enough about what I'm buying

Heres some advice, cryptocurrency is about 10 years old. And is only exploding now. YouTube is about the same but it exploded years ago. It took several years for it to become a part of daily life. Crypto isn't part of daily life yet. There is room to grow, so while the industry is primed, it's up to you to decide which one you want to go with.

If you buy and your afraid of it dropping, then there's only two things to do. Hold through the dips (don't use money you need to pay rent with) because you don't realize lost until you trade your tokens back for usd. The other is to trade for a loss before it becomes too great, but that's easier said then done given the volatility of the crypto market.

If you don't know what you are doing then learn by seeing, hearing and then doing it with smaller amounts.

There is no such thing as a free lunch. If you truly believe in the crypto market, it's best to learn about it and put in less sleep after work and more hard work to learn and understand the nature of the crypto market.
