Request will have a massive pump in the coming days. Easily 3-4x from here. Strong team with great advisors. They are most likely to succeed.
How much time is left to wait? There's no reason to hold a huge bunch of tokens. Tokens are only needed for fees, but there won't be any extensions/applications on relevant levels in the first year. Just have a look at the roadmap.
Hey, the APIs are going to be released in the Q4 2017 Colossus release, after the main-net release in Q1 2018 there will be applications available for you to send Requests and a good chance of extensions / plugins built using the APIs too.
