How did these new coins come about, there are so many. Are they owned by company? There are some with weird names. Are they all real or fake?
Are you talking about all the cryptos that are listed on coinmarketcap?
There are more than 1360 at the moment. And no, there is nothing weird with them, there have been a lot of altcoins listed in there since a few years, but during this year there have been more than 1000 newbie coins in there.
THere is nothing wrong with this, and they are created by the founders of each team, they do not have any coincidences because most times they are created by different people.
