Good points and I also hope they are able to increase the block size and get transactions moving faster on bitcoin. If they can manage that without a split then bitcoin is seriously going to moon.
Which puts me in a battle with myself buy a shit ton now and hope for the best or maybe reserve myself into some alts till this all smooths out and perhaps regret it if it moons lol the struggles are real.
The other issue that if bitcoin rockets, the alts will probably do so as well (from past experience). If bitcoin tanks, so will the alts. I think you need to be in bitcoin (primarily) and if you don't trust it, out into fiat. I see the alts moving with bitcoin currently and I don't see that changing in the near future, until more mainstream adoption and the recognition that there is a difference between them. This will also need most alts (without a valid use case) to die off. Not a popular statement I know, but 900 instruments with no real life application outside of speculation is too many!
