1. transactions are still fast. in fact they are nearly instant. it takes only 3-5 seconds on average to have a transaction propagated throughout the whole bitcoin network of thousands of nodes. it is the confirmation that takes time.
2. the fees are low. they only went high for a short time and that is what happens when bitcoin is under heavy spam attack and there is nothing anybody can do about that.
3. nothing about security of bitcoin has changed, i don't know why you are listing this here!
4. it was never supposed to be fully anonymous. if someone said otherwise they were confused. read the whitepaper.


that just means you don't understand what a decentralized currency means.
