In 10 years when XRP's liquidity begins to absorb Bitcoin's institutional liquidity you will see Saylor gradually shift to a Multi-coin strategy like Trump is with The Crypto Stockpile.
The Millionaires, and Billionaires don't care about Bitcoin, or Crypto but will gladly use it to benefit themselves.
Saylor only wants to profit from speculators, and play greater fool/hot potato with Bitcoin.
And when he does sale Bitcoin will go back to its intrinsic value.
But that doesn't bother people who use Bitcoin as Peer-to-Peer money, that only bothers the NGU HODL-ers.
Bitcoin is Money, use it!
