1st of all when you buy a coin. You see all opportunity of coin, launching date, graph reading, publocity, places usage of coin then you are decided thats its good for future or not.
All peoples are now that many coins are generating in the world but all coins are not best for u because some are scam coins but not all.
Everyone see that coins are growing very fast like a car but you need reviews of public, friends and specially social media sites they will confirm the reputation of coin.
I know in the world crypto trading is the best work. So please leave all investment programes just invest in crypto trading programs. Hold your coins for long term they will never loss to you.
Thanks
