"Bitcoin has never been hacked", Bitcoin has had 2 software bugs that allowed to print billions of Bitcoins, one around 10 years ago and another around 1 year ago,

The problem Bitcoin has is not hardware attack, but software bugs, and most of Bitcoin mining is based on ASIC hardware from centralized 4-5 manufacturers, you can't mine Bitcoin with home computers CPU/GPU. Also a fake Bitcoin was created in the name of bcash to try to take over the original Bitcoin. So the network is under attack by the miners itself

And the miners dump the price constantly to pay for electricity. More places accepted Bitcoin in 2014 than what accepts in 2019. Nobody is using Bitcoin after 10 years, only 2.8 million wallets with $1000 in them. And many have multiple wallets. The biggest problem Bitcoin has is no marketing budget. Nobody has big enough bag to pump the price or get it out to the mainstream masses, EOS raised 4 billion dollars, more successful than what the Bitcoin guys ever made, and they have a marketing budget
