Best Alt of lowest fee, dev, API, appdev, security a privacy?

[jubalix]

If I want to developed and application for a lot of users say 100K plus and make say 10 transactions/day, I need smart contracts e whats the best alt platform eg

KOMODO? (they seem to have dex that idicates it is fast and cheap)
Graphene?
Waves?
NEM?

LISK (but dev of side chains never?)
XPR is not a crypto and to expensive to set up.
Stellar/Lumems? (but that locked up)


EOS seems out because too expensive ...
Eth is too slow and expensive ...
LTC and DOGE do not seems to have the contracts side...

I recommend you in using Nem, but its new invention Nem Catapult. It is a full decentralized system
I have been testing their Nem Catapult so far and it is very fast and easy, you can make mosaic as much as you can. And the process is very simple.
you can check it here https://nem.io/catapult/
other than Nem, you can use Waves too. Graphene is very slow for me not recommended, I have tested Seer project before it is based on Graphene. The rest, I never use it.
