Lots of alt-coins have been cheaper and faster over the last 4 years, still are.
An old saying
"It is not about the return on your money, it is about the return of your money."
Bitcoin is more than just speed, I would advise new investors to go and read some of Satoshi's posts.
Besides, I personally am glad more bagholders are leaving Bitcoin, for every one bagholder that exits come 10 new excited, interest, entrepreneurial investors ready to take Bitcoin and business to the next stage. And one less pump and dumper.
Central bankers fight price corrections, Bitcoiners must embrace them. They clean the pipes like a good plumber.
In reality they are not. The arguments about Bitcoins are related to it not being scalable. Just because an altcoin with next to no usage compared to Bitcoin is doing okay, doesn't mean it would actually be okay with the same level of usage.
