well, i don't consider those cases to be "spam", it is normal usage even if i don't like it. and there shouldn't be any restrictions on them in my opinion. there is just too many exception cases that will end up harm regular users too. that average Joe that spends every 5 days might want to purchase two things in one day some day and his second purchase would cost a lot more just because of a bad rule that was supposed to prevent spams but it can't.
??seriously??
so again 3000tx a block. to match the 'blockreward' of ~$62k a tx needs to be ~$20
so your ok with a $20 tx... so lets start with you being ok with a $20 tx FOR EVERYONE.. FOR EVERY TX.
now theres those that want/need to use the blockchain every 10/20minutes.. they pay the ultimate price of $20.. which you would be ok with...
where as those that only transact once every 5th day pay $20/144/5=~3cents..
yes occassionally if they need to buy something, and then realise 10 minutes later they might need to buy something else straight away they will end up having to pay $20.
but the current "fee war" is fixed at everyone paying $20 anyway.. so infact the times average joe is not 'spamming' he is saving money. and learns to form better spend planning habits to not be so impulsive.
again as for those that want/need to spend/spam regularly and cant form better spending habits. they can use the niche service..
win win for everyone.
i do find it funny how those loving the fee war forcing everyone to pay a $20 premium EVERYTIME. then claim any way to make people more frugal/ organised save money is a bad rule
