BITCOIN: How does it work. Can someone simplify this phenomena

[yoniman]

Hi TRFers, Bankers, accountants and BITCOINERS.

My brother-in-law-learnt I am buying another watch.
He said better to buy a Bitcoin.
Naturally, I told him to eff-off as I m still tragically waiting for a 116710 BLNR and 214270 Expy 1.

Bitcoin here in NZ cost NZD$20,100 +- or approx US $14,385.00.

Have you any TRFers personally bought a BITCOIN? Thoughts and advise on this who have actually purchased will be appreciated?

Intend to buy a minimum of at least 2 Bitcoins for the long - haul for like 7-10 years. return.

Any thoughts, comments and experience on this BITCOIN?
It's all media hyped now and I think not the right time to buy.
And who are the TRUSTED sellers?

Thank you
