But how high is the threshold before it truly becomes concerning? More than 80%? 90%? Bitcoin is a limited resource and there's twelve out of twenty of the biggest investment banks and asset managers in the world that wants to gain custody of Bitcoin in some form.
Altogether they control TRILLIONS of wealth.
It's probably why Bitcoin developer Peter Todd has currently been saying that he's open to the idea of an inflationary cryptocurrency.
It is important to emphasize "in some form", which means that all those who provide futures trading services are not directly related to Bitcoin, while everyone else, regardless of all those trillions of dollars, will still invest only small percentages directly in BTC, and it is also important to emphasize that BTC is not the only thing they are interested in when it comes to cryptocurrencies.
The question you're asking therefore doesn't have any concrete answers because we can only speculate on how much money will really go towards Bitcoin, and whether at some point Bitcoin will become a game only for big guys. However, all of us who have been with Bitcoin for a long time have one big advantage over all these institutions, and that is that we have long understood what Bitcoin is, and they are just beginning to understand it.
I hope that regardless of the price that may be formed in the future, some people will not agree to sell their BTC, even for very tempting amounts that will be offered to them. After all, our strength is in numbers, millions against ten or twenty companies - I think we have a chance.
