Bitcoin has been running for 8 years now and the blockchain is less than 90 megabytes. If we double that size in the next 4 years, then the blockchain will only be 135 MB.
You seem to have MBs and GBs confused which is very out of character. I'm guessing they are typos. Might want to correct them.
Hard drive capacity will continue to increase, and it will most certainly outpace the growth of the blockchain. Disk space gets cheaper by the day.
You've been excellent at answering many questions on many threads then you come out with this tired trope. Please don't disseminate this rubbish. It's not, and has never been, a solution. It is the bitcoin equivalent of "Have faith that God shall provide".
Bitcoin was
designed with the advancement of technology in mind. The whole difficulty adjustment thing is to ensure that, even as CPUs get faster, we continue to get blocks that are 10 minutes apart on average. If you feel that expecting technology to continue to advance is wrong then you should find some other hobby. Forget about bitcoin.
