It is always good for a coin to rise naturally, than for it to quickly pump because of that news and then dump when the news is not available again.
you are missing the point with altcoins! there is no "natural" rise in altcoin market and if there were then it wouldn't be worth investing into such coins because they wouldn't really give you much of a profit.
what we have in altcoin market is pump and dumps and that means unnatural rises that happen fast. so the only thing you have to do is to adapt to these types of pump and dumps and be fast about getting in and out of these shitcoins for the most amount of profit.
