I only buy, and never sell my ADA because I believe in the team and what they are doing so much.
Just to put it out here so that I can revisit this later, once the layers on top of the base layer starts coming online from the end of this year..
You should cut loss when the market is crashing. I hope that the market would turn side ways so you could recover your loses. ADA is a good coin but it is not immune to red market. Holding is good if you buy on the deep.
