buying wave is a good call, but i don't expect more then a 2x price increase
It will not even get closely to $9 until 2019. Don't waste your time on it, start invest to other coin like OmiseGo or NEO or Stratis
OmiseGo and NEO are pumped now. This is a bad time to buy, wait and see where the correction falls. Stratis on the other hand was pumped a while ago and now its just stagnant around the same price. I wouldn't recommend any of these.
