All cryptocurrencies are in apocalipsys constantly.
No one use BTC to pay $60. Yes, it's a problem, but not yet for common usage. Why? Because btc is not used for majorities, only to make money.

The best way to kill btc is easy: all governments has to legalize btc.
Consecuencies:
1. A lot of people buy btc to high price.
2. Markets sell btc.
3. Price fall a lot.
4. Common people can't use it because they can't pay $60 because high price of transactions.
5. Big markets win, as always.
6. Btc becomes a bubble for everyone.
7. People trust again in fiat.

A lot of specialists talk about altcurrencies only for its technology. Yes it's the principal part. But everybody has to understand that these characteristics are not important for markets... yet. They only need an Exchange.

And well, I think your message could have more sense next year or in two years if anything has not changed.
