I am still confident about the long term prospect of cryptocurrencies (and bearish on the short term prospect). However crytos remind me of the dotcom bubble burst in the early 2000s and thus eventually only a few cryptocurrencies will survive and thrive, just like only a few internet companies had survived the burble bursting and thrived. I personally believe the eventual winners are most probably bitcoin and ether and these are the crytos that I will buy and hold. Buy crytos only if we are afford to lose everything and don't buy crytos with leverage. Be accountable with our own trade and cheers!
