Is there any website or Organization where CryptoCurrenys register itself just to make sure that particular cryptocurrency is trustworthy? If no then I would love to get some tips that help me filter a real cryptocurrency and a fake one?
Mate, let me just give you a general idea not specific to PiNework or anything, there is no official or government led regulatory body for the cryptocurrency niche. What we have like SEC is non existent here.
You have to decide on your own whether something is worth putting your money into. Now let me make this clear, 99% of the projects that are pitched are failures from the start. They cannot generate any inherent market or bring anything new and useful to the table - most project are just bringing old concepts in new names and then going bankrupt. The investors get tokens for funding that project when end up with zero value, essentially a scam and one in which you have no power to go legal.
Now coming to specific details, it is better to keep your VC/Angel investor dreams to yourself if you want to keep your money safe. Invest in bitcoin at lower price but not in any shitcoin like this one. You will regret the second choice after a few years.
