There are many answers to this question and I am looking forward to see everyone's opinion.
coins will be harder to get. combine this with more adoption (more people will need it) and you'll get a price raise. no adoption increase and it will be suck for everyone.
By harder you mean it will require double the computing power to produce the same amount of coins.
yes. because the halving halves the block reward from 25
BTC to 12.5
BTC. ofc the difficulty can affect that also.
The difficulty will be much higher than before,i think ever 2 weeks the difficulty raises and with the halving it will be much more harder to mine.
