Even with the negative factors and valid ones at that you listed there, I haven't seen businesses moving their funds to alts when they know to convert to fiat, most of the alts will still need to be converted to Bitcoin first. For me, I have not seen any alternative to bitcoin in the altcoin world but hopefully with gradual development one of them will come to mainstream and I can join in.
I think even with higher transaction fees there are enough benefits to bitcoin that many people will still deal in the currency. But switching to another coin seems the least likely option a buisness would choose. They are looking for stability.
