This is so true ... 2-3 years from now, if you stay in the crypto game you will be one of the grassroots investors in alt-coins.
The barrier to entry to buy most of the coins is huge to the average individual! For example if you want to buy Quarkcoin you have to first buy Bitcoins (not an easy thing to do) then go to an exchange and buy Quark. Most people dont have the patience to do that, as well as the know-how. Ask your parents you want some bitcoin for Christmas and they will have no clue where to start.
And what about the mining? Took me 2 days to get a small rig setup to mine litecoin with all the hardware & code setup.
This is the beginning...
I absolutely agree that this is the beginning. Many of us are in it to make some quick money but I personally think it's more about waiting and trying to innovate. So far, it looks like we're on the right path and we will have a bright future. Cryptocurrencies will only be expanding through time, so yes I agree that it's only the beginning
