Are you planning to trade with the BTCs or just holding?
Just holding
If you just want to HODL then you should move your money from the exchange as soon as you make the purchase. Do you have a plan where you will be keeping those coins?
If you don't, then you should sit and read a bit about securing your funds. The crypto currency is nothing like the monetary system we all know. You can lose your funds forever by doing some small mistakes and there is no coming back. I don't want to scare you, I just want you to know that you have to make a plan how to keep your funds safe. A hardware wallet seems to be the best option.
Yes, I have a Ledger hardware wallet that I've been moving my coins / keys to. My plan is just to keep everything (I'd only buy BITC) on that same wallet. Would there be any reason to split them up and put them on more than one wallet?
As an aside, what's with the hodl spelling? I guess that it was just a meme that cuaght on at some point?
Anyway, thanks for the response!
