Anyone telling you to buy is giving you bad advice even if buying bitcoin become profitable.
You should use whatever money you have to start a business, or work for someone who know how to run a business well to gain experience and knowledge. Not wasting your time on speculation.
Uhmm.. did you get lost? This is the
speculation subforum where people discuss and ask questions about speculation. OP already mentioned he wants to buy and is just asking for our opinion when to do so. Get out of here and join some business forum or something if you don't like speculation or investing in something.
