I'm not here to spread FUD before you start throwing accusations at me. I'm just saying though, Bitcoin is increasing in price, and it's probably a very wise idea to sell your coins and hold BTC at this point. I'm however not referring to alts like ETH, Tezos, LTC and the other solid ones out there. I'm mostly referring to the projects that have not followed the roadmap and didn't manage to deliver and let's be honest, there are plenty. Probably anything not in the top 15 in CoinMarketcap is not worth investing it (with few exceptions).
And apparently, there is some confusion within the community about price increases in CoinMarketCap and people think that everything is going up right now, which is not the case. The green numbers you're seeing in the price page don't represent much. If you click on the coin though, you'll see the price in Satoshi... that's the one that should be increasing.
That's true not all altcoin have great price right now even the the price of bitcoin is continously growing, but it's good also to take part of altcoin that have great value and potential not all needed to dump. For me I will hold both btc and altcoin not just one coin to sure that I can get some profit incase I lose to one of that coin.
