I will advice people to analyse market and the coin that want to be used to trade or invest before buying such coin because some coins are just existing to take away your money before it becomes fully dumped.
Why not advice them to stay satisfied with investing into bitcoin instead of wasting their money on shitcoins as 99.9% of the altcoins currently trading in the market are worthless and won't last long as more shitcoins will still come over to overthrow the current so called bitcoin Killers. The altcoins aren't actually introducing anything much that's new to the industry instead they're recycling past ideas and basically surviving on the fact they can be traded on exchanges without this all alts are worthless.
