In some sort not,but the market graphs now are so wavey that you cannot clearly say about whats gonna happen to the coin you are holding but if you have strong sense that what you are holding has great potential no worriesnor feel danger.
Yeah right, if you have a strong reason to holding your coin, why not? just as you're sure that that the coins you buy have great potential
to grow then it's not a problem to take risks by holding the coins. because not all altcoin end up with a scam right? some even have high prices..
