I've followed the bitcoin/altcoin market for quite a while now, I was also in the mining business for almost half of last year. Indeed the crypto market esp de altcoin market is very and I mean very volatile/ it's not that liquid at all so the moves can be influenced very easily by investors willing to gamble sth like in a couple of thousand dollars range.
The BTC is much more steady but going slowly downwards/ I remember last year in April, the price was somewhere between the $600 range now it is stuck at $250. At that time, it was still profitable to mine - not necessarily BTC but other altcoins - but now unless you have free electricity, you don't stand a chance. I follow closely XMR aka Monero altcoin which has great potential on the long run but you can also profit from the short-term swings if you know how.
One rule of thumb for those who want to try the crypto market: the technical analysis is pretty much useless from what I've seen, there are other factors you must consider before making a decision to go long or short and keep in mind that a small speculator can pretty much influence the market.
