I bought $3M worth of bitcoin recently and I am waiting for the next bull run.
Whoopee-doo. A measly 166 BTC is nothing.
Prove it. Sign a message from your UTXO. And prove you are hodling in SegWit addresses that start with a
3 instead of a
1.
When my friends tell me they bought BTC, I replied congratulations and I'm happy for you. I don't see merits proving it, especially to you.
