I think that everyone involved in the market contributed to the ATH of bitcoin, I meam the hodlers should be a big part of that because they are the ones that are whittling down the supply and making the prices go higher because they create a sense of scarcity, we also have to mention the lost coins as they are a big contributor too.
If it's not for the people who hold bitcoin, there won't be any market on it. But those facts that you've said about lost bitcoins forever which makes the supply lesser will contribute in the long run.Thanks to them, but thanks to the buyers also. Without them, those sell orders wouldn't have been filled.
Indeed. Not only those who sell their Bitcoin, but the buyers also have a big role. Both of them have a big contribution to support the Bitcoin ATH. I also one of them who sell Bitcoin, but only a few of all the Bitcoin I have. So, just thanks to me, guys!
