I'd suggest that to skip myetherwallet or mycrypto entirely and a) buy a hardwarewallet, like metioned above or b) have a look at MetaMask. Using myetherwallet is just too risky for someone who is new to the space because there are scamming sites all over the place.

There are a lot of guides about MetaMask:

Or simply watch their video:
