As I'm expecting the "last dump", and the market usually does the opposite of my expectations, I would say that we are very close to the bottom... 😃 The second boring thing is going sideways, which could happen for the next few months, easily...
Regarding alts or HIVE, I tend to ignore and not think about... lol... 😃

How many BTC holders still around to sell? How much money influx from the institutionals, who essentially just started their entrance?

This is something that I was questioning a long time ago... I think that we will come to the moment when some people will try to "count" the balances of all these "buyers", and the count will be over 21M 😃
