I think that holding is not the best idea nowadays. There are so much now tokens and ICOs which are failing and loosing their prices.
Can you look OP? he ask not about ICO or token price but he ask about bitcoin price in the future.
Hodl bitcoin and hodl token are very different, it's too risky to decide hodl token in the long term. But for hodl bitcoin will always make you believe that the price of bitcoin will high in the future.
