those who are having bitcoin's have a bright future bcoz it is one of the top most business activity and ledging business in todays and futre generation .lot of surveys says that have huge future to bitcoin holders and traders in this digital world I do agree with you that if a person HODLs at least their BTCs, you can acquire and take advantage of its volatility for maximum profit.
Do they have advantages because it will help them pump their few dollars or because it protects wealth against the original inflation we have been fighting worldwide? There are other firms that have invested billions of dollars in other assets as a hedge against inflation and are doing well without owning bitcoin.
The thing is, bitcoin beat other assets in many ways but has in own flaws too and having a single UTXO of it as an investment is one of the best decision anyone would make today, nobody knows what tomorrow will tell but sure it has a way increase in price by virtue of its demand and supply.
