I will post here some coins that I consider them to be scam coins from a crypto point of view:
Mcoin made by byxpress
leocoin
onecoin
swisscoin
all this coins are only MLM shit and don't have anything in common with cryptocurrencies
Don't invest in them.
Trumpcoin could be added to this, the bitcointalk thread was the most amusing clusterfuck in months, though.
SPEC
Algorithm: Blake-256 Proof of Stake (POS)
Circulation 6 million
Global Supply 12 million
Staking reward 2% annually
they made at least this shit, all other coins didn't even bothered to give out the specs .... all that coins are centralized coins that are not respecting the terms of the crypto.
and you have to buy "hardware" from them to mine it .... guess why? because there isn't any mining going on and there is no hardware
