i'm sorry..
but can you explain what the chart mean ??
The chart shows the number of bitcoins in existence and the instantaneous rate of monetary (supply) inflation as functions of time.
Is it worth to keep BTC for next 10 years ??
No one can possibly know the answer to that question, but everyone I've talked to agrees that, in 10 years, bitcoins will either be worth nothing or a whole heck of a lot more than they're worth now.
Has a long way as it needs to be capable to use by the average joe for it to boom
