You hold is what you do... if you missed riding the correction then just stay in the position you're in.
I admit I broke my own rule today, do decent research.
I woke up to all these tweets by that PND jerk winningtrades4u. he was spreading tons of hype about a 10x(!) increase based on end of todays closing price. I was like "that cant be correct you cant automatically increase the price of a coin." He links to the steemit/Reddit posts about this supposed 10x increase and i thought "okay, so it might be 10x the 30 cents, thats decent, buying at $1.50 seems reasonable for that."
Bought, and then tanked :p
Been doing research all day, regret this decision and now realize the twat did absolutely zero research. I messaged him about why hes claiming a 10x increase on end of day price and he said "I got in on the presale on bittrex last night. Tomorrow it is 10x!" I was like "presale isnt on bittrex, its straight from Dev, wtf are you talking about". He blocked me thereafter. Lesson learned. Do OWN research. As such, idk what to do here.
