Thats not well know altcoin to invest but you can try search it first the security before you buy. but in my opinion better to dont buy.. use coinmarket cap those top 20 in coinmarket cap are legit to hold for a long time.. it takes a long time before you can make a profit but its more safe than a newly altcoin..
that is right. It is better to buy the large market cap coins. They have much less chance to be a scam coin.
This the only thing that you can know that the coins is not scam.. unlike you are just invest your money in newly release coin that you didnt know if it that coin will stay long.. or its just a shit coin or scam coin.. the top 20 are the most people who are holding for a long time because they know that they can make a profit if the price is increase not so fast it takes a long time..
