"The only point I'm making here is that with the power of exponential, small regular investments will be much less profitable than a big early buy at a low price."

Exactly what I was reinforcing, but investing all your savings into a single coin will end badly.

Best way to invest is to either short trade on an exchange, invest into ICOs or research companies, place funds based on long term investments. All which can be done with as little as 5$ a month with massive returns over the long term.

Bitcoin in my opinion is only useful today as a transaction currency but only because its widely accepted. If you want a real good long term investment with small amounts of money look into VERIUM / VERICOIN, TenX, Ripple and Golem.

Found a great video, alt coins vs bitcoin investment. Great advice in this video.
DON'T CHASE THE HYPE!

Good luck!
