But I think the recent rally is not really a bull market, it's just a big rally in a bear market.
Because most altcoin did not have a good rise, only BTC had a big rise.
How do you define "bull market" or "bear market"?
If we had an overall up trend from late 2015 to late 2017, are we out of that uptrend, or just in a short term correction? That would not necessarily be a bear market, even though the trend turned downward for a period of correction.
Regarding alt coin rise, what the fuck are you talking about? Alt coins were pumped into a state of craziness, and they had a few pumps that might have been riding on the tail of bitcoin, but also had some of their own dynamics, depending upon which of the shit coins you are referring to. Some of the various alt coins and ICOs are continuing to be pumped far beyond any feasible value that they have, yet concededly, there pumping potential has dried up somewhat in recent months, and perhaps some of the froth was removed (at least temporarily). I am not so presumptuous as to assert that I know where alt coins are going to go, but there is likely still enough ambition and permission in the crypto space that they are likely to have some more pump periods that go much beyond any kind of real value that they are likely to provide to the space, except for bringing a lot of dumb money into the the space that might get smart enough to migrate some of the value over to bitcoin, perhaps?
