1. Sell it now and invest in other promising coin/token.
2. Hold it for long-term (Atleast, until you have recovered or BEP)
3. Hold it and buy other promising coin/token with your money obviously.
4. Is there any other option?
Yes there are surely other options:
5. Buy more and average down
6. Sell it now and buy more of it when it goes down further
Remember the reason you bought it in the first place. If you feel that your reasons for buying back then were flawed then you should probably sell it. Otherwise, buy more.
