It is not even remotely comparable to raiblocks. Here are some reasons:
- Team: Not even a name somewhere
- Code: 5 Commits, last one from 2015, 1 generic Contributor
- Website: Looks like the year 2000 is calling
- Volume: In the past around 30$, since all the stupid money joined in december it increased to around 5k per day
- Vision: No idea - why is it called spacecoin?
- Roadmap: Generic Buzzwords without any Deadline
- Whitepaper: Nope
- Community: Nope
Stop waisting your money on "projects" like this. Raiblocks had a clear vision, dedicated team and new technology (DAG). They didn't do a lot any marketing, but if you did research back then, I were able to see that the project was not just a wast of time.
Also, if you invest money in it, I doubt you are able to ever get it out of it again since they have no volume at all.
Edit: I notice your shilling the coin all over the place. Better search for something which is actually worth the effort. Just shilling scam coins without any kind of innovation does not help the crypto space in any way.
