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.

Well currently it's fair to say that but what if there's a solution for a possible change in block size which will be agreed by all ? That's why I hate conclusive statements because nobody knows tomorrow.
