Bitcoin was already trusted in around 2011. Mainly in a drug community, but still.
The new currency needs security and a more user-friendly usability. The attention will come quickly because there is already a lot of attention on the subject. Bitcoin had to catch the attention on the entire subject itself. If a crypto emerges with better qualities, then people will start jumping cryptos fast. It's the nature of products that are supported mostly by hype. Support from hype is a fragile thing because people will get amazed by new alternatives very quickly. I think that doggecoin perfectly showed the nature of bitcoin. You don't even need a better quality product and simplistic lowbrow hype was all it needed to become quite popular.
Are you fucking joking? Bitcoin had no credibility in the eyes of the outside world back in 2011. SilkRoad was very small back then so you can't even say the online drug community trusted it. One fuckup after another along with the slow slide in price gave the few people who had heard of it ammunition to shit on Bitcoin at every opportunity. It all culminated in the infamous Rise and Fall of Bitcoin article in Wired at the end of the year. I need to stop now or I'll have nightmares about Bruce Wagner's grin and the mybitcoin heist. Where are you Tom Williams???
