No Saylor didn't tweeted it but with the speed they are accumulating it won't be a shock that they own 20% of Bitcoin supply and let us assume he doesn't do that but anyone can do that if they have money, if a person i really really really rich then sure he can buy 20% of BTC and that's not fair to other people,
See tbh I also don't know am I right or wrong I just had a thought and wanted people's opinion what I am thinking is right or wrong, but trust me HODLING BTC is not a good thing ONLY IF YOU WANT IT TO BE A CURRENCY, otherwise if you treat it as a Digital Gold which was it meant to be then HODLING is not at all a issue.
People will not be holding Bitcoin if it has no value and if everybody is thinking that it will not pump again and will soon be zero in value. You see, a big number of Bitcoin holders are speculators and no speculators will wish that what he is holding will be going down...it is always up and if that is the case then a person will surely continue to be holding that coin or Bitcoin.
The problem is that if Bitcoin has no chance to go up, I don't think there will even be 5% pf the holders will remain holding it and I don't think either anybody will be excited about it. Bitcoin's volatility is a two-edged sword repelling some people and attracting a bigger number into it. Is it good as an asset and not as a currency? Maybe yes and there is actually nothing wrong with that because that is not the fault of Bitcoin...that thing is being decided by us the people. And who knows what the future may bring...
