Still ranking 9th place and this makes Terra one of the most valued coins this 2021
https://coinmarketcap.com/currencies/terra-luna/So Yes this is one worth currency to invest, this has a long way to go so support it or forget it that is the only option you have.
Terra-luna has moved very well in the last few months so that it can occupy the 9th position in coinmarketcap because I have also seen this coin when it was still outside the top 10 of coinmarketcap and at that time it was also experiencing a very good improvement, so obviously this is not wrong choice.
