What to do?

I hate to be the guy to buy at peaks. It’s silly to me and I’ve been burned every time. Ethereum is obviously a leader in crypto and hindsight has seriously been bad lately. When all crypto dipped big time, I had my finger on the buy button for one Eth coin….I didn’t believe in crypto fully and still don’t because I don’t understand it. Being nervous lost me thousand’s.

I bought a ton of doge before it’s rally and made a killing.

I have $500 bucks to just play with and am wondering if it’s silly to put it in now at the peak? Or should I just keep taking profits from other stocks until I have enough to buy one Eth during a dip?
