Bitcoin still traded and i think thats indicating bitcoin is not a buble. I think its called buble if bitcoin price become zero and no one trade bitcoin anymore. Its true that bitcoin price drop and many investor moan about this but i think its very usual in any market that the price always volatile
we could called it buble if no more investors interested in this market.but now , the fact was different.BAKKT even will launched their futures trade for bitcoin and ethereum.no more people said it as bubble again.
I am agree, we saw in market that bitcoin still having biggest daily transaction volume and its very liquid market. I am believe bitcoin is legit investment and will survive for long time. Its good to hold bitcoin for long term because we can sell it instantly and very liquid when we need money
