You have your own opinion about bitcoin and other investors have their opinion as well. It might be good or bad depending on how you view it, but there have been a lot of people that got their life changed through it, though I have seen some of them say bad about Bitcoin and try to discourage others that it's no longer what it used to be. We know that there are risks involved in Bitcoin because of how volatile the price is and other challenges that are said to likely happen, like the 51% attack. Anyone who's investing should always have it in mind that it is a risk, but that doesn't mean we should give up.

How strongly you believe that ethereum is not being controlled by Chinese miners? You must have been drunken or lost a big money in trading/gambling while composing this topic. Do not state anything without proper reasoning. Ethereum must be a crap as it was being used by scammers to suck innocent investors. Ethereum cannot be a money forever whereas bitcoin is already proved itself as a capable competitor to replace dollar and gold from global reference currency and medium of exchange.
