Next bitcoin might be pushing it, but it could be close to it or be at par with the current well traded coins like ETH, LTC and XMR. It is promising, that is why people are really investing money into the project and the devs are very active with the community. I guess, after launch we could expect a sudden rise in price, so buying now would be the best choice.
Their are so many coins which went good in ICO but as soon as it gets launch in exchange their rates go down and it is natural because in the starting their will be dump through lot of options, like bounty coins, weak hands who seeing small profit are just selling it seeing small dump in price. So i will wait till launch and then i will buy it and keep for long term.
I find myself using the same strategy lately for several reasons. In most cases, you can obtain the coin/token/asset when it becomes available for sale on an exchange right after the ICO, usually for a better price than participating in the ICO (due to the eager dummies who want to make a quick penny & sell them much too low, and/or those who received free tokens via a bounty and/or signature campaign and just don't care what they sell for).
Secondly, with so many ICO's these days, it becomes a pain to keep track of the ones you have participated in, & then afterwards have to jump through a ton of hoops to convert your ICO tokens. Lately it just seems much easier (and often cheaper) to wait until after the ICO & purchase right after they are available on an exchange.
Lastly, waiting helps prevent bad investments at times. There have been a few ICO's I had planned on participating in, ended up not participating in for one reason or another, and watched the coin/token/asset plummet for a number of different reasons. I realize startup capital is often the only way to start a new project, but have seen many succeed without an ICO (or very little capital) at the same time. Initial distribution in the form of an ICO is becoming a "thing of the past" in my opinion, & as I've seen others become very successful with no ICO's, I know alternative methods are possible (and equally effective)!
