The coin prices moved up so fast the last couple of weeks a correction was inevitable, I noticed this on Wed when my coin portfolio jumped several thousand dollars in just a few days. Don't panic now, just slowly buy the coins that you like as they go down, that way you will have more coins when the prices move up even higher when the correction is over. Of course you have to have some capital available to buy with, so you want to sell off some coins when they reach new highs and wait for pullbacks to buy. When everyone thinks that alt coins are done the correction will be over and the next leg up will begin. Don't be one of those who sell at the bottom and buy back in when the prices have moved up a lot.
