For me the best altcoin to invest for now is Envion coins. The reason being that as it stands it has a very good future prospect. By 2018 it would be higher.
For me, the best investment strategy is to classify my investment into long term investment and short-term investment. The long-term investment should be on bitcoin while short term investment should be on Altcoins.
I think it's a good idea but you should make sure you get your strategies right from the start because there are so many unsuccessful ICOs out there.The first thing I think you need to do is to put together a good and efficient working team, develop a good working paper and a roadmap. With these you should be able to achieve something good.
I believe anything can happen at any time. Although bitcoin is the strongest coin as we speak but if ethereum should continue at this pace it is currently moving in few years it might meet up with bitcoin or even surpasse it.
With my short experience with crypto world, I think bounties are worthwhile, you get involved in their campaign and at the end of the day you get something but one must be careful concerning what to invest one's time in because some of the projects might not be successful and as such nothing wil come out of it.
I believe it is possible if the team has a well designed project but I also think the Pioneer team have to bring more people on board for delegation and for the success of the ICO.
I think It is advisable to always conduct an adequate study on any ICO an investor intends to invest in. There are so many ICOs out there, so one must be very careful.
