I will definitely participate in auctions. Now I choose Acala, it's a great project. Overall on the investment, my DOT tokens will be locked up for 2 years, but I will get the winning project tokens in return, which can be sold at a profit.
I participated in moon beam and it was too imaginary. It was really amazing to surpass aca. At the same time, I also participated in Astar. Personally, I am more optimistic about this project.
