For me it is Bitcoin. I feel much more comfortable when i keep my money in it. Some alt coins drop in price so fast, but Bitcoin looks much better.
Yes, I'm the same with you. My favorite coin is Bitcoin. You know, bitcoin is the number one choice for investing. And really what you say, I'm calmer when I have Bitcoin.
Besides that ETH can also be used as a second choice, especially now the price of ETH is down. I think this is the time to buy ETH.
