Cryptocurrency dropping

I see with all the cryptos dropping with what I have invested I am just going to HODL(hold on for dear life) with it all and buy in this time of dipping of them. Also, I was trying to get a new gpu to help myself make some some coin with mining and holy cow gpus have doubled and tripled in price in the last month. To top it off it is very hard to get a hold of any, I had to order one in order to get one. One place told me not to expect one from them until the end of February. Talk about total nuts in the head and Ebay good luck with it there they are all jacked up on their prices. So I will just hold out for them when they come back down.
