Agreed and can attest to this. Faucets 8 years ago gave away some good amounts of bitcoins, like 1 bitcoin per click or so. It wasn't worth my time then but later regretted. Such an opportunity is rarely found now. I wont be surprise that some set of persons still lack trust in Bitcoin regardless of how it has proven itself all these years. Because in 2014/2015 people never really believed in Bitcoin they dont believe how a digital currency could be outstanding and promise a revolutionary technology in it, they all felt its one of this internet scams then, but yet these people still trust the internet system.
This is another proof that as time progresses, it becomes more and more demanding getting Bitcoin. Who will imagine that there was a time people were getting as much as 1BTC free! Then it was even easy to accumulate Bitcoin unlike now. In the future, we might even look back to today as the time it was cheaper to buy, this is a possibility and the reason we should endeavor to avoid another regrets in coming years.
There are good ways to accumulate Bitcoin, if such a person still lack trust or fear of investing now then h/she can buy some hardware, setup and start mining. Those who couldn't buy Bitcoin then should not miss their participation in accumulating now or might regret later for miss.
Unfortunately, mining is not a cheap to start and sustain. In addition to the cost of hardware, there is cost of electricity, logistics, land/rent (depending on the size of the mining farm) and other costs that may arise in the course of installation. Furthermore, competition in that industry have increased, necessitating the use of expensive and latest equipment to remain profitable. This means that mining is not a risk-free option for those that do not trust Bitcoin.
Besides, will you spend money to mine what you do not trust? Anyone who can mine Bitcoin really trust that his business will yield profits.
