ADA when compared to ETN actually does have a lot of prospect in the long term. If you want to consider the team, the current support and the possibility of seeing a huge development in the long run, I would not expect ADA not to do well hugely.

Nonetheless, the OP is giving himself a short term profit when it comes to gain and if it is profit he is so particular about in the short term, I would say that approach is not actually a very good one. Sure, we are all looking to profit from our investment, but anyone who understands the market will know that there is no way you can say how far a market would go in a specified time.

The most important thing is to invest in what you believe in and be hopeful. Generally, in the long run, a project that has a good team and a product will always do well.
