Hello, I am new in this forum but not new in cryptocurrencies, I started trading cryptocurrency in 2016 and my first cryptocurrency I bought that time is vergecurrency and other penny coin. And I returned my money in bundle because they have good tech and very good team..So early this year I noticed that a lot of coin is now scam and failed promises. So please if you want to buy any coin don't go to coinmarketcap only because coinmarketcap can list any coin without verifying it well, just go to their telegram group and ask questions I think this can help you stay away from scam coin...
I agree...there is a good dose of luck of course, but you must always do your own researches...for example watch Elicoin in livecoinwatch ( not in coinmarketcap ) , is not an ICO or bounty... it's a coin with low mc, low supply, PoW whit cpu, no premine, active dev...only trading it on CREX24 for now...do you own researches in the thread in bitcointalk:
https://bitcointalk.org/index.php?topic=3028302.0..I bought them 2 months ago and if you watch it in livecoinwatch you know why now I laugh very loud

people are too stupid for DYOR and got scammed by ICO or bounty...just my 2 cents...hope it helps...cheers
