Don't sell your bitcoins
The scale of Bitcoin is completely unthinkable. We won't act on where it's going, but the truth is that just as it's easier to dispose of fiat rather than gold, the same goes for Bitcoin.
Remember that for a long time, for thousands of years, people always kept gold stored and used silver for simpler commercial transactions; gold has always been the store of value, the well-known "GOLD." No one really offers their gold for nothing; if you have to take out the stored gold, it has to be done for a good reason.
Gold is still people's preference today, but gold loses to Bitcoin. The price of Bitcoin since 2008 has shown a certain exponential growth, and the highs and lows have eliminated skeptics along the way because Bitcoin is not for skeptics. I believe that those who saw BTC worth 10 dollars regret not having stored at least one BTC for today, seeing it worth around 50k.
Don't sell your bitcoins yet. The price will skyrocket, it's not speculation, but those who know BTC know that there's no other way; this thing will be worth more than 100k shortly. And for those of us who don't have millions, we may not be able to buy 1 BTC at some point; the most we will be able to get is a few satoshis of it.
So, what path to follow now? Invest, buy more, a little each day or week. We don't know how expensive, rare, and valuable it will become.
Bitcoin is secure; destroying over 51k nodes that keep it alive is no easy task because just one active node is enough to restore the entire system.
If the CEO of JP Morgan stated in a debate that "Satoshi Nakamoto will appear and delete all BTCs," he probably wanted to cause FUD, but either he pretends not to understand how the master cryptocurrency works.
The only true blockchain where Bitcoins can be transacted is the Bitcoin blockchain itself. Several other blockchains created after BTC are fragile, and I do not believe in their security. But Bitcoin is the DIGITAL GOLD OF OUR TIMES.
