The greatest insight in cryptocurrency trading is:
Better to not make a profit than to incur a loss; this is the highest wisdom.
Consider this:
If you lose 20%, you need to earn 25% to break even.
If you lose 30%, you need to earn 42.8% to break even.
If you lose 50%, you need to earn 100% to break even.
If you lose 90%, then you're in trouble, as you need to earn 1000% to break even.
Profit and loss are never equivalent, so it's better to not make money than to lose money.
