Appreciate your reply but what is 5 sats/b and where can I find them?

X data/byte is the feerate of a Bitcoin transaction. Sats are smaller units of a Bitcoin and bytes is the weight unit of a transaction.
5 SATs/byte means you pay 5 satoshis on every byte in a transaction you create.

Thanks for the link! Could you tell me what is vMB?

VMB stands for virtual megabytes, it's related to the transaction weight above, only in this case it is virtual (using segwt) to allow for more size within a block and reduce fees.
