This will increase the price of coins, but you need to improve the system so that there are no failures due to a huge number of transactions.
I agree. And I think that the bitcoin blockchain system can never maintain a huge number of transaction daily if the whole world starts using Bitcoin. There will be another altcoin strong enough to sweep Bitcoin away
Those problems that we are experiencing will surely be fix when all the nations are already using and adopted bitcoin. And it's a thing that will make the price to pump, the demand will be higher and the supply will be lesser and I guess when it happens, satoshi's / bits will be more valuable by that time and has a very good value.
Well you're idea is acceptable and if nations will adopt bitcoin I think many hardworking people will have profitable income in the future.
