Short resume on the petro:

We are now with version 4 of the petro. Before we had petro as ERC20 token (version 1), then as Nem token ve:ptr (version 2), then as Nem token ven:ptr (version 3) and now we have the petro as a dash copy (version 4).

None of those versions ever hit the market: A small number of petro:ico tokens, which were supposed later to be changed to petros, where sold, but investors can’t do anything with them except admiring them in the now useless petro wallets for version 2.

Also petros of version 4 cannot be bought or sold:

• One can buy “certificates of purchase of petros” at the counter of the government agency responsible for the petro (SUNACRIP);
• one can buy “petro saving plans” over the web (millions of pensioners received – as a gift by their president! – such saving plans, worth 0.1604 petro);
• and one can buy “petros” over a web page (a clone of uphold). In the last case they credit you petros, but don’t give you any petros. (The web page says since its launch, that “soon” you will be able to pay with petros.)
  

None of these purchases is reflected on the blockchain of the petro: As of December 15th there were less than 115 addresses on the blockchain with a positive balance. You can look at a list of almost all addresses, accounting for more than 99.99% of petros here: https://pastebin.com/KEJR6iGF

Most of the addresses with positive balances are older than the official launch of the petro (version 4) sale, others are newer but serve as backing for, for instance, the saving plans, certificates or petros credited. Example: First 4,000,000 petros were put aside for the saving plans, later on these 4,000,000 petros were devided into a few smaller junks:

https://explorador.petro.gob.ve/address/p5wfevURqApT9s2Yc4ifjjbddrodfSTmZr (now zero, but on 12/15 still positive)
...

There’s no petro wallet. Since many weeks there’s an announcement that the petro wallet for windows and linux will be coming soon:  https://www.petro.gob.ve/wallet_eng.html There was an android wallet, but it was retired and there is no announcement of a new one.
