Hi

New to the forum, sorry in advance if my questions had been answered already.

Would like to know

-if buying bitshares is the only way to purchase bit20 ?
-can I buy bitshares or Bit20 with GBP directly?
-can I purchase Bit20 at other exchanges?
-what will happen if bitcoin is out of the top 20 list one day?

Many thanks

Best regards
JGV
