I must say, the first thing I had to look out for after seeing your thread header was if you own at least some fraction of Bitcoin at all. As, one can’t go ahead talking about benefits on some commodity that you don’t possess. Of course you might find them on some piece of material somewhere but, nothing talks about benefits more than when you’ve got that commodity in your possession and experience it first hand.
If you read the OP's post carefully, you can understand that he is talking about himself as a late investor.
We can also understand those newcomers who do not yet have a dollar in Bitcoin, but they will still call for investment since everyone understands that newcomers need merit. Or even being a late investor, having bitcoins worth some 20 bucks, an increase of five or ten dollars already makes such an investor rejoice.
Where I disagree with the OP is the call to invest no matter what. Investing despite not having the right knowledge will always lead to loss, further disappointment, and an unlikely return to investment, especially for people who save on everything.
Therefore, haste and the fear of not being on time are always very bad. Walk slowly, and be sure you know what you're doing.
