I just watched your interview on the X22Report Spotlight, which I thought was very good. I've been interested in bitcoin and crypto's for sometime, and although I wouldn't consider myself an expert, I feel I have a good understanding on this subject. I'm interested in your thoughts regarding the size of the bitcoin block-chain. I think the ledger is currently running at 1TB, but this will increase as more people use it. This ledger can not go on forever, there will be a time when the ledger becomes too big, or am I missing something?
