I don't think 2018 is a good time to invest in Bankera, i am sure Bankera will be a high dump when it goes to exchange, people can buy Bankera tokens from exchange at much cheaper price. anyways good luck!
I suppose it will depend on the success of the ICO. If the ICO sells out, the market cap will be around 180MM, which is a pretty insane amount. Then yes, we'll see a major sell-off. However, it is more likely that the ICO will not sell out. The pre-sale was open for quite a while and 2.5B tokens were sold. So they're going to sell three times that amount at a much more expensive price 0.010 (pre-ico) -> 0.017-0.025 (ico). I highly doubt they'll get even close to their hard cap.
Perhaps if the ICO is not that successful and they burn plenty of tokens I can see the prices remaining stable post-ICO.
However, I do like this project which has the potential to achieve mass adoption. Also, they are taking their time to develop the product before launching their ICO, which is very positive. This might mean that they might actually come close to reaching their hard cap. We'll see. Either way, this is an interesting project to follow.
