I do believe for both BTC to be 30k USD or even higher and ETH 3k USD or higher. ETH got a high probability to go higher though as of its record of adoption, technological and systematical advantage than BTC it may have some downfall for now that cause its stagnancy but I believe it will rise higher it even have the potential to compete with BTC in the near future as they say. About this IOTA I don't believe it will even reach that there is alot of competition out there for lower rank alternative coins.
