with the big correction going on in crypto currencies what would be the best buy ?
Best buy? Best buy is effected by number of factors like time period you would like to hodl or exchange you using. You can't name one coin randomly.
Moreover, considering present crypto market I would like to suggest you to buy coins for small periods. Nowadays Bitcoin is more or less stabilize and other coins are booming. So follow signals, analyze market and choose best coins; buy low and sell high.
