i don't think that would ever change the fact that bitcoin can never be used as a currency as it is so volatile. It's price literally flies and drops every other hour or maybe minutes. Maybe some firms or companies may accept them but its difficult to show cash flow so it will not be used as a currency overall.

At the moment even the value of bitcoin is somewhat stuck within 6-7k. Do you guys think that there is any other crypto/coins are worth investing in and why?
 

i think you should not gamble your house and your memories for BTC as its value can go down if people start dumping it,
look how it came down 7000 dollars in a matter of 4 days, so you should not risk such kind of thing!

if all the people start dumping them but the banking giants(investing in bitcoins) wont let the value of BTC to decrease to that level

is bitcoin core better than blockchain and the others?

Due to how volatile prices of bitcoin are, they cannot be accepted anywhere in the world. 6000 dollars down in a mere time of 4 days! WTFFFF
its price increased by 20 dollars while taking a screenshot LOL
