What puts me off when using bitcoin is the delay in transaction confirmation.
You know, having to wait for days most at times for my transaction to be confirmed.
I think the confirmation will not be that long at this time, unless you insist on using a very cheap fee under the standard fee, of course you will receive your transaction within a few days, if you want to get a quick confirmation then use a default fee or more, then you will get fast transaction
Yes, the amount you spent on the gas will give varying results. Filling the transaction with less would mean a slow travel. A standard gas fill gets your transaction travel time on the norms. And giving it more than the standard will get your transaction to reach its destination much faster, sort of a special 1st class travel with traffic lights all green.
