Yes, it's pretty much the truth. You can literally become set for life, should a single coin which you invest get its time in the spotlight.
Let me explain by using en example: Had you invested just $1000 in DigiByte exactly one year ago on this day, your crypto networth would have been exactly $171 428 US. That amount of money is enough for any smart person with a capable brain on his shoulders to turn into the life he always wanted to have. That kind of money, made from a mere $1000 one year ago, would put you in a position in which you could easily draw the path of the rest of your life, if you don't screw up, and if you are smart, which I'm assuming you are.
The number of such growth cycles are many, and the above example is hardly the last. A new, ambitious coin project may appear tomorrow which, in turn, will increase yet another 300 times in value, just like others have. NEM has grown 1489 times since 2015.
The amount of motivation and hope you technically should feel should amount to the gods in the skies, so why are you not learning everything you can about every single new crypto project?Why are you wasting your money on video games, the newest Android phone and other useless shit which makes you into a lazy consumer rather than a wealthy investor?
Look into the future and connect to your future self; what would he have wanted you to do today? Forget tomorrow. Your best friend is you 1 or 2 years into the future. Tomorrow's you isn't going to matter. Don't sell it off after a week. Do you think the NEM investors would be happy today had they only thought about their tomorrow's self? The answer is clearly no. They are very happy today actually.
