Crowdholding stands out for sure, it is a sure and steady progress rather than the flash bang you see nowadays.
They have made a lot of decisions that solidify their platform and user base first rather than go for just profit.
This ensures that crowdholding will have a solid future.

Conceptually, I really like the idea of it and use it frequently.  It's a lot more meaningful and productive to give feedback and test stuff out direct from companies.
Beats signature campaigns which is just busy work and telegram which has just become a chaotic mess for most channels.

Technically, the platform is terrific.  I've experienced no problems at all.  It's bright intuitive, and easy to use.
Seriously, a beta that is this useable and solid is incredibly rare in the crypto world.

And then, of course, everyone's main focus: investing.
Crowdholding just barely released their token (yup) and it hasn't even shown up on coinmarketcap yet.
You can get it at idex and coinhub.
So you have a company where tokens are going for 1 to 2 cents.
Has thousands of new users with a crazy exponential growth this year.
Has new companies jumping in every week and new tasks daily (not to mention deep onion is on their platform)
Has a fantastic working product and a marketplace in development for Q3 2018.
To call this undervalued would be an overstatement!
