- And as of captcha it is really not in our hands and surely we can not get rid of captcha for security reasons! And we are using solvemedia captcha which is the most easy (if you are unable to understand the words of captcha please refresh the captcha )
You got that one precisely backwards.
Captchas do NOT protect against bots, captchas prevent regular users from using the site.
The reason is simple: There are Chinese companies paying workers pennies an hour who solve captchas for a job.
This is where bots get their captchas solved and this is why captchas cannot tell bots from humans anymore, simply because on the captcha part bots ARE in fact humans.
At same time the captchas increase difficulty NOT upon suspicious behavior, but based on the amount of times a given IP accesses a captcha.
This means, on a site like Coinpot.win, where users have to solve 10+ captchas every 15 minutes, ALL halfway active users will run into absolutely unsolvable scribbles within a few hours.
This also means, since those "professional" Chinese captcha solvers are FAR better in solving even the most difficult captchas than regular users could be, a site using captchas will FOR SURE within a few hours have EXCLUSIVELY bots for users, simply because regular users aren't able to solve the captchas anymore.
If I look at myself, after I signed up, I was using the site for about 2 days really frequently, then captchas increased difficulty and I cannot solve them anymore.
The only solution I have is using less captcha protected websites and since there are PLENTY of faucets paying better than Coinpot.win I rather use my limited accessability for other sites.
Only late at night, like past midnight CET captchas usually become solvable, because traffic on the web goes down and therefore captchas reduce difficulty, that's when I make a few claims, but compared to my first 2 days on your site, it's less than 10%.
