In my opinion, one should take knowledge about any good coin without buying any coin now. Then you can make good profit in your own intellect.
15 days will give you a good time to learn a lot. You do not invest in the work. It will be good for you.
Correctly doing the results of your own opinion when researching is a solution that is at your own risk. no other party follows the risk, maybe there is a friend who suggests buying the coin but it doesn't match expectations is a disappointing thing that really exists. maybe for people who know crypto for a long time can distinguish a good coin project in the long or short term...?
