Will owning 1 btc make generational wealth?
If you have 1btc now in your wallet account OP, I can say that it is better to hold it for awhile and put or transfer it to a hardware wallet first so that it is not prone to hackers. Because holding Bitcoin right now is a huge thing for sure, especially if it's at least 1 bitcoin.
Just try to wait and just leave it in your wallet account for at least 1 more year so you can see what will happen to your hold of bitcoin, which can definitely double or even triple the amount of capital you have now.
