Time goes to now. The price of ADA is $0.2 when I bought ADA at $0.39.
As almost thought, The price may down again in 1 week. It seems I sold ADA now and buy it at a lower price could be a good choice.
I thought for whole morning. Yes, I choose to hold ADA and wouldn't sell it although the price will down.
Honest, the wallet of ADA is so hard to use! I could not sync the wallet succeed.
