I think that the main thing about cryptocurrencies is that it has some significant advantages in comparison with regular fiat.
Anonymity, wide distribution and decentralization are key drivers for people to use blockchain and crypto
BUT, it's still has disadvantages which discourage people. Like long delay between transactions

I really believe that it depends on how our information security technologies will develop in the nearest future.
If blockchains will provide the acceptable level of confidence in digital money, that will work
otherwise, any promotion won't have any effect, 'coz people wouldn't invest any money, 'coz they will be afraid of fraud of any kind.

And whatta u plan to do if BTC won't rise up? 

Depends on what do u want, which budget u have and what do u plan to do in the future with ur investments.
BTC is hard to invest now, but gold is not
BTC is more about earning money and gold is about saving it

It doesn't crashes it under the correction
Don't worry it supposed to get back even rise up higher
I believe it'll be about 20+k for BTC

I think that the main disadvantage of BTC is that i hadn't bought it earlier))
But to be serious, i believe that BTC is not really convenient to be an everyday currency. Its price is too high so u actually can not buy anything for it.
Moreover, according to features of blockchain of BTC it's too slow to be used in our life.

I really believe that in month or month and a half it will rise up to 20+ thousands per BTC
It's really time invest if u'd not invested a week ago when it was lower than 10 thousands
