Does it have to be new? I mean maybe you can invest into something older? As we all know here the new coins that are not tested by time are usually bad investments and that is exactly why many people suggest staying away from them until they prove themselves to be a good contender. I personally wouldn't go into anything that is not 6 months old, I probably stay away from all the new ones under 1 year and aim at staying away from under 2 year as well.
I personally have bitcoin, ethereum stuff like that but if I had to do any PoS coin I would probably go with tezos, cosmos, waves and stuff like that because like them or dislike them but we all know what they are and who the creators and how the coin is doing which is all it matters for me and at least I can be sure for what I am investing into.
I've got this feeling people dont want to spread the word about what they would consider to be good startup coins, they want to mine those in peace first and load up as much as possible. Afterwards when they have what they want they tell others to buy and mine.
So does it have to be new, this poll is about new coins, not old projects with an already high marketcap.
The coins that have been tested by time, then you basically missed the train at the station so to speak in regards to getting in early when the price is low and the pools arent swamped with miners, like todays Ethereum and other older projects are.
