I agree, but in my case, with LISK (ICO) and or buying an altcoin at the high, I have a few altcoins that I've not sold yet. Mainly due to being stubborn because I got into them
too high. (Not a lot of $$$ but they sit none the less). Or in the case of Litecoin, I actually bought a mess of LTC when it was around $85 USD, because I thought it would go up
due to 1) mimblewimble protocol and 2) the halving coming up in a bit more than a month.
Again, except for the Litecoin nothing major in the price wise category.
In the past, not sure it applies now, altcoins would USUALLY (or the ones I've still not panic sold) will follow Bitcoin price rises eventually. It usually takes a point where
Bitcoin sits at a price sideways for a bit...say a week or so. Altcoins never go up along with Bitcoin on the same % scale when BTC is pumping, if I remember right.
So only keep such altcoins around that you can speculate with, have little $$$ in and are stubborn. I probably have too much in Bitcoin vs USD, but hey, it is how I roll
if this whole BTC and crypto stuff was not dangerous, where would be the fun! (Sob!)
