I too have never seen anybody using it in at least North India. In fact, I never ever heard anyone even talking about it. Unlike many people here, I am actually very close to rural life in India and I couldn't spot this phone. South India may be?
I don't know how it was the best selling phone in India.
Bitcoin’s success in Venezuela is because it is a inflation hedge. It has allowed Venezuelaeans to hold on to their savings and out of reach from the government’s ability to confisticate wealth via inflation.
> ...proof of stake will make this sort of attack 10k worse. With proof of stake there is essentially no resource cost.
This is not true. For a 51% style attack on a PoS chain, you need to acquire a majority of staked coins. Each coin you buy increases the cost of the next coin, (demand/supply and all that), and the price of the coin increases exponentially as an attacker accumulates 51% of the coins.
With PoW, cost of acquiring hashpower is linear (acquiring the last 1% costs the same as the first 1%), which is why PoW is easier to attack.

Not really. All you need is a controlling vote for enough confirmations. At 51%, you’re very likely to have a controlling vote. Below 50%, it’s still possible.
