I have btc on Electrum mobile wallet.
I want to buy a hat using crypto from an online vendor.
Vendor accepts several crypto currencies.
It's a one time purchase.
I don't want to spent more than 20 cents in transaction fees.
I want the transaction confirmed within a couple of hours.
What are my options?
I thought of Lightning but that is still going to cost me a lot in transaction fees when opening a channel. And since this is a one time purchase, it defeats its purpose because, well, might as well just directly purchase using btc.
So...what can I do?
Sad to say that these transaction fees are way out of your control depending on the network that you are using. In BTC from segwit to segwit, expect that the fees are not that cheap even if you set it to low but longer waiting times.
However, if you are in a rush, then you have no choice but to pay the higher gas.
Some networks that have lower transaction fees are XRP, TRX, MATIC, etc., which are probably your best bet to save in terms of gas fees. For BTC? No can do especially about expecting the confirmation in a couple of hours.
