Tell your friends who are interested in BTC but too retarded to learn how it works that you will offer a security service.

Offer to buy/sell/store BTC for them safely in paper wallets in a safe. Charge them 5% of the BTC they want to buy as a one off fee for security.
Make them sign a waiver for them acknowledging the risks of cryptos.

You could expand and offer passive portfolios which you would only need to rebalance once a week or so. Allows more normie money to flow into crypto while offering an investment system that is far simpler than trading cryptos.
