I cashed in on 28k back in 2023, told by a lot of people that I'm stupid as fuck cause bitcoin's already got as big as it got and it will never pump any higher than 40k in the near future. As of this moment I'm still holding and have already more than doubled the money I put in.

You can't be too late with bitcoin especially these days, there will always be a higher price point that you will be able to reach given enough time. At the current state of bitcoin, at least in the foreseeable future I can safely recommend investing on bitcoin as long as you hold it long and don't sell every time the coin drops a cent like these paperhands.
