Will we ever use Bitcoin for day by day use? Buy a bread, a phone, a car, an appartment? Or Bitcoin will more likely be a way of just storing value and we have to rely on altcoins to use them daily?
I prefer your second opinion like BTC to be storing value. The costs prove it us. I dont think BTC will go down to costs of alts so we will use them for daily.
bitcoin in the future will be a coin that can be used everyday if bitcoin is legend in various countries, and the use of altcoin I think only limited to be traded alone can not be used for day-to-day transactions because bitcoin more dominate for use transaction.
