Good points to ponder. I've been thinking along these lines a lot. Will Bitcoin last? I'm sure crypto will, but individual coins are at risk.

What has institutional money been buying? Is it all in BTC? Does that even make BTC still worth holding? Will BTC go the way of Myspace and get replaced by better cryptos? Will is slowly lose market dominance until it's just one of the many?

I suggest that investors remain flexible and well informed. It may be a big mistake to say "I hold BTC and that's it, I'll check back 10 years from now to see how it's doing". It probably won't be a mistake, but one should not rule that option out.
