it is not the mining, but the the trust of people may have a limit, if you are holding bitcoin you will also experience all of the upcoming forks.. some people are still adopting on the last fork and bitcoin transaction fee is really pricey.
The mining of our bitcoin today is not what it was years ago and it is not easy as before. Only big companies of miners will have a profit or those people with big capital for mining hardware can do it today. :(
