If those holders are selling, there should be either huge sell orders or lot of liquidity.
either 1 year of endless dump and -99% of value at the end. But you right, there always will be holders. Holders that will sell to NEW holders at 50% loss. New holders will sell to very new holders at 50% loss and so on. Until price will not fall from $1200 to $0.
If that is true, then there should be plenty of liquidity any given time. Byteball still has 25 million marketcap, you can't sell 65% without being noticeable.
It's funny how some holders get extra furious of spreading FUD every time when price drops. Some other probably hold their heads because they are speechless how shitty can one community be that it undermines its own investments with FUD even more. Thanks for all the FUD, you are doing great job.
