It is a good initiative as till now I have not seen any crypto-dedicated bookmark website to provide backlinks. Well, it's a good thing but don't you guys think it's not needed, like a dedicated one, because the change of rule in Google policy against crypto might hurt it, as it's dedicated? I know at this age that's not so soon to happen.
"Google policy against crypto" mainly refers to crypto ads, but that too has been changed and there are no more obstacles. Many times I have seen some proven scam or phishing sites as highly ranked on Google, their policy is if you pay enough, they have no problem with what you do.
Plus you won't get so many website requests, and there are other bookmark websites that have 90+DA and a good PA as well. While you have 2 DA and 3 PA which is not so good number. I know the website is only 28 days by age.
Domains with a low DA are not very attractive for backlinking, but since it is just the beginning, they may increase in importance over time.
