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.
Much better to hold the coin that you know will grow like now that bitcoin is growing and feel that alts will be follow to bitcoin. So hodl it for now, we know that it's hard to predict what will be the price of coin so be observer too.
We are apparently seeing some altcoins moves higher but the others still sleeping dead. If you have no patient, will actually made a decision to sell. That is the common problem right now, and we can't stop them cause in the first place, it is just a waste of holding those nonsense coins too long without expected returns, better to sell it and invest into different coins. Maybe it will be good by then.
