Not shallow to me. I can’t get a bank account, credit card or Paypal, so cryptocurrency is the only possibility for me to work remotely and shop online. (Cash works for local stores and apartment rentals, but local work for cash is difficult to find and most online stores don’t accept cash by mail.) People rarely mention the financial inclusion benefits of cryptocurrencies, even though it’s the only way to send money online that doesn’t require government ID.
I earn less than $1000/month in Bitcoin/Monero, which I withdraw to cash to pay for food and rent, which are necessary living costs. This is much lower than the $10k limit you described. I can’t get a bank account anyway and use cash for P2P trades (Bitcoin ATMs, cash in person, cash by mail).
