I feel 2017 gains was a once in a lifetime opportunity and we won't see anything like it again.
January 2017

Many of the top 100 coins with a considerably small investment could have made you a millionaire today, and congrats to those who are.
$10000 in ETH at the time and you would never need to work again.
I just can't see these gains happening again, but anything can happen
I've made almost $2 million profit through invest a lot of my money at january last year. We will never see such a great thing again because the crypto will become mainstream investment place in the future.
As far as i can predict about the future of crypto will be shining in the future.
Remember the price of bitcoin was around $900, this time the price is around $12k and maybe next year we will see the price of bitcoin $20k or even more.
I read so many companies are interested to issued their own token or try to make tokenization for their assets which become a good thing for all of crypto holders.
