I was just looking at the coinmarketcap table since 2013, I was surprised in what I saw, many coins topping the charts then are now almost non-existent, we need to be careful of the kind of coins we hodl especially for long term. Most of these projects just die after the initial hype.
You are absolutely right. Many coin's jump in the market and after couple of months there's value drop so much. Actually you need to check very carefully that project which you interested. Watch their movement, analysis there road map, see their social activity and more thing. If you think things going to wrong don't to be late sold your coin. We all know about Bitconnect.
