The fear of losing is greater than the desire to win! So people trade or sell before a ten years timeframe.
When the stocks starts its fall towards 0 people will do incredible mental gymnastics, clinging to any shred of hope that things will turn around and they will revert their losses, so it takes them much more time to get out of the bad investment.
For me and probably many others, when expediency isn't an issue, BTC works great.
