An idea investor sees Bitcoin investment on a long term perspective, and having volatility as Bitcoin functionality it is expected to buy and hodl in other to have a compounded value of his investment over certain periods of time, Bitcoinis is a world class asset that is a store of wealth and value for future profits maximization.
Investors don’t just buy Bitcoin for holding shake and take profit later, some invest their money on Bitcoin as a means of reserve and inheritance for their children and extended family where they can transfer it as an asset to their family in time to come and the value might have either doubled or even if still in same price which is not possible inflation won’t affect it most compare to how it would have affected cash stacked in a local bank account which the financial system will still charge you for maintenance and other reasons which they use to debit someone.
Yes, in essence bitcoin is used as a tool to store wealth and multiply the money owned, whether it wants to be an inheritance or anything for himself or his family it is a variable that can change over time, but in outline the purpose of investing in bitcoin is to seek the benefits that we can get from accumulating it and storing it over a long period of time.
Inflation in my personal opinion is a separate force to increase the price of an item including commodities and investment assets, such as gold or bitcoin, with inflation prices getting higher and lucky for those of us who store the value of our money in bitcoin.
