Algorithm can be changed to avoid new asic development
1 - The is no asic resistant algorithm.
2 - Changing the algorithm of Bitcoin is impossible (without killing it).
everyone is supporting greedy companies, that is making money by producing miners for dummies, that will most probably get back their money.
No one like them but without them Bitcoin doesn't exist. Your bitcoins are worth zero on a different fork.
You can do it right now yourself : clone the Bitcoin code, change the algo, that's it.
Now you are on the temporary asic resistant chain but no one will ever give you a cent for your bitcoins.
