I saw a good tip on
Youtube (Spiffing Brit). Basically follow @elonmusk on ƚwιƚƚeɾ, turn on notifications, and if he boosts dogecoin or another lesser crypto currency (dogecoin is very much a lesser one, it jumped a bit when Elon boosted and then fell back), buy a bit, and when it goes up a bit, just sell, don't wait, just bank a bit of growth. Don't get greedy. Bitcoin is quite acceptable as risky investments go, but transactions on it are registered publicly, it is very much not a crypto currency, except that it good enough as a way of giving money to people treated as lepers by the usual payment systems.
