Bitcoin dollar averaging

I see a few posts about people doubling down or adding more longs. It's cool to go long, but it's another to add more money to a loser. The one thing that is worse than being wrong is STAYING wrong. It is a fail safe strategy that your account will eventually end in ruin (except cash accounts). Averaging is a martingale, you are more likely to break even or even make money. But one of these trades will wreck your account. I've lost too much money, it was an expensive lesson.
