If you have a fear of missing out on profiting from a shitcoin, you're being really, really stupid--and greedy.  I can understand that emotion when you're talking about bitcoin when it's booming like it did in 2017, but for one of these typical pump & dump shitcoins?  Come on.  You'd have to be a complete noob to fear missing out on one of those.

I agree that everyone should avoid altcoins that suddenly start rising unless it's because bitcoin is rising concurrently and only if you're talking about one of the better altcoins, and there aren't too many of those.  When I think of pump & dump coins, I think of those shitcoins on Yobit that go for 1 satoshi and occasionally you see them jump to 2 or 3 satoshis and you know someone is doing that on purpose.  It's easy to pump a coin like that because it doesn't really cost that much and there are usually tons of sell orders and no buy orders in sight.  Those are the coins every trader should avoid at all costs.
