In the year 2130 all of the Bitcoins will have been mined and the only reward at this point is transaction fees,if most people are using Bitcoin just as a store of wealth, then there are very few transactions, which means there is very little reward for mining and so a lot of computers would pull out of the Bitcoin network. Would this be a problem? If large Bitcoin transactions occured sparingly in 2130 and beyond, would the Bitcoin concept still work?
In my opinion there will still be transactions but with the consequence transaction costs will be high because that is the market law.
The smaller the number of transactions, the higher the transaction costs and vice versa. But I'm sure bitcoin in the future is not only an asset for wealth, but is also used as a universal payment tool in all sectors.
Because on the other hand there are still many altcoins that might still be able to coexist with bitcoin.
