We're all long-termers, I think few people would claim otherwise. But what's long term mean to each of us? I suspect that's very different.
BTW, don't you at least sell every now and then for needed cash?
I would disagree on that we all are long-term holders, many on this forum trade a lot, or sell everything they earn in any way. Patience is a virtue that not everyone has, and if you need money for food and other basic necessities of life, holding is something that is almost impossible to do.
I almost never sell any coins, but I pay for goods&services with Bitcoin on a regular basis. I believe it is a great method of storing value, few years ago Bitcoin was only $200, today almost 100 times more, and in next 10 years only sky will be limit.
