I took a few attempts in several languages to find out how many people use crypto to pay for goods and the outline was kind of unexpected. Now here lets have a look. Do you sell online and accept Crypto?
I do sell online and I definitely wouldn't mind being paid in crypto. I haven't had any client who wanted to pay in crypto though.
I use bitcoin extensively through my Electrum wallet. I buy the services and goods I need, accept payment for my services. In general, I am very pleased with this.
Total proceeds are the aggregate sum of the fair market value of all your crypto at trade/sell time across all your transactions (shown per taxable year on the tax page). In other words, the total fiat-value equivalent you got across all your crypto sells/trades.
