I would hold them and I will. I don't have that many bitcoins but I think the price goes up so I'm making lot of profit with that I have. I would totally risk to be a billionare
May I ask why? Holding while the price is falling is almost as stupid as selling while the price is climbing!
Those people called believers confidently think the future price of bitcoin sooner or later would bounce back due the factor of bitcoin gonna be the most wanted thing to invest more than gold and considering time after time the supply of bitcoin to be mined getting harder, the market would have high price, as simple as like that.
The thing is even then it makes no sence. If they had sold all when the price started to drop and would buy again when the price start to raise again then they would still make way more money than with holding.
The thing that those people who have no idea how to trade properly make you think it's doesn't work , it won't work and better just holding. Imagine when the price move at $9,000 - $1,000 range. How much money you can get while holding yours ? You just missed the opportunity! At least we have different way to reach our goal to make profit as much as possible.
