These people have really no idea about what differentiates Bitcoin from Ethereum. What makes Bitcoin the only legitimate store of value, is that it doesn't have a public creator or owners, it cannot be controled or changed by a small group of people, and it will only ever have a finite number of coins (21M) so its price will naturally rise with mass adaption as miners won't be able to keep up with the increasing demand and more and more people will use it as a long term investment or a safe haven against unstable national currencies, rather than a method of payment.
Ethereum can reach 3x the marketcap of BTC this year and than it can crash to zero in a matter of days as people realize that there is nothing behind all the crazy ICOs.
Many shitcoins and tokens will burst when the bubble pops, but Bitcoin cannot and will not be stopped.
