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
Sure already only %3 of all people on the earth invested in Crypto, we have a long way to go, next big Wave would be in 2021you better get ready for this.
For those you was wondering why I said 2021, 2021 is the year that we have BTC Blockhalving.
