Hard to answer this but I like to think of it this way:
1. Are you long term hodler? If you think Ada is going to the moon and you're a hodler, then it really doesn't matter if you buy at 2.40 or 3.00, especially if you think it's going somewhere
2. On the managing your emotional outcome side of it all: how do you think you'll react if it does jump and you missed out? how do you think you'll feel if it plummets if you had it or not?
Best of luck!
