Yes. Getting Bitcoin will only get more difficult because of the price, and adoption, over time. However, if Gavin and others like him did not do what they did, Bitcoin would probably not be where it is now. That is now part of Bitcoin history.
But imagine if you were part of that early history and you actually used Gavins faucet to get some free Bitcoin, do you think you would actually keep it to this day? The honest answer for most people is probably no. You probably wouldn't have seen it as a future goldmine. More likely, you would have: spent it, lostit or completely forgotten about it.
You are very right sir, most things happen to pave way for a better tommorow, every single days that come all we grave and pray for, is for things to get better than initial however, what we should be more concerned of now is on how to accumulate more stash of our coin other than channeling more energy on the past.
Secondly, no matter how high in value bitcoin goes or reach, there will always be more investors to invest in it with the help of the DCA method.
