The best pick this month would be lots of coins so you need lots of advices, you need to know the roadmap as you ask for this month. OAX's prototype will be released at the end of june so it could be one of the good picks for this month.
Now, this is the case I talk about every time. This dude right here do have OAX as his signature and apparently promoting it. Now, he may be biased or promoting for the wrong reasons but what I want to point out is that does not take everything in face value but do proper research yourself. I do see most people here are promoting where they have already invested or where are currently enrolled for bounty hunting. I guess that is not the right way of suggestion in an open discussion. If you think Dent is good enough to invest in and have some prospects, then stop asking and make your own decision. No one will be there to give you back your funds if you lose them to any shit project, so be careful.
