Im not sure about that but buying crypto its almost INSTANT. I am not sure if you can buy it with blockchain but you can with coinbase(Both are crypto wallets i use), coinbase takes 11 days to clear to be able to use if you buy it thru them. I use coinmamma to buy bitcoin and it goes straight to my blockchain wallet cause its linked. Usually the only way it doesnt go straight into your wallet is if you gave wrong wallet codes.when i deposit it only takes about 15 minutes if that to deposit to go thru and withdrawals take around 24 hours or less. Now i have had a time when it took almost an hour on bet online. Hope this helps and maybe im misunderstanding what your saying. If so im sorry
