Let's say your alt coins rises to 1 mil. Are u still investing? What happens if it pop to 600k? Ur waiting again for the rise. I think I'm dumping at 1 mil.
It depends on the altcoin that you hold and also depends on bitcoin chart behavior. If Bitcoin is in bull run i will sell my altcoin and buy back when bitcoin started to dump or stable. You need to diversify your portfolio if you want to avoid loses.
