If you're looking to enter the market now, remember three things: 1) Don't go all-in; spread your buys out; 2) Don't just keep stop-losses in your head; write them down in advance; 3) Until BTC reclaims key resistance, don't chase altcoins blindly. It's not about who has the biggest balls right now, it's about who survives the longest. If you don't understand something, play it safe; cash is also a position.
