[SERIOUS] Curious About Jumping In During The Bull Run

Okay so long story short, the last month I really started looking into crypto. It started when I came across a video comparing the early days of the stock market to crypto now, and just how similar the two are. With that said, I've done my research about crypto and the technology, but I'm a little hesitant to transfer funds into crypto now with bitcoin and other cryptos being so high. So I thought I'd ask here where people are much more knowledgeable: if you had $0 in crypto and saw the market now, would you hold off jumping in, or would you jump in anyway?
