They do not have a gaming licence from Curacao otherwise they would listed it. I think you are wrong because there is no evidence they are registered in Costa Rica.
It seems they are not listed as an company anywhere, they are not a company it is just some scammer trying his luck.
The scam website URL is:
https://1xbit.com/Their Twitter URL is this:
https://twitter.com/1x_bit The link in the Twitter page goes here: bit.ly/2E02tGm (which is: crypto1xbit.com)
Here are the WHOIS:
https://whois.domaintools.com/1xbit.comhttps://whois.domaintools.com/crypto1xbit.comI have contacted the license holder Antillephone from Curacao about my case regarding to 1xbit, but they told me that 1xbit is not familiar to them.
I am afraid they are licensed in costa rica. I spent hours and hours to find data about their company, but I can not find it anywhere.
