I think this will be right time for the crypto currencies adoption, because if after three years of holding everything, we won't be able to achieve at least 30k USD per Bitcoin, we can quit and close this industry.
I also believe that in three years cryptocurrency will be more popular and we will be able to take advantage of the many opportunities that they can give us.
We only have high hopes to see the price of coins go up again because I see Bitcoin experiencing a bad decline now. Ethereum and other types of coins will probably have a worse price.
