Hey rabbit_year
 I also have this same thing and Freewallet has taken 600$ from me and I am in iran ans this is alot of money, that I made through video editing with tears.

 Have used free walet sine 2020 and they say they added this inactive fee in 2022 and did not send me an email and they say they Don't have to because the changed text on website,  and they have unclear wording that may or may not allow it :

  We reserve the right to alter, amend or modify these Terms from time to time, in our sole discretion. We will provide you with notice of such changes by sending an e-mail, providing notice on the homepage of the Website and/or by posting the amended Terms via the applicable Freewallet websites and mobile applications and updating the "Last Updated" date at the top of these Terms.

 And the only way to sue them is through Indonesian arbratation the Indonesian National Board of Arbitration ("BANI Arbitration Center") , the Arbitration would be under Indonesian law and not sure if under Indonesian law they can do this or not.

 Do you think it's worth it to file an arbratation case?

I have an idea
 You could convert the AC voltage from your generator into pure DC and then convert that into 220v AC with an accurate frequency

  Do you mean find a math realation between these numbers?

 first   x: c994b69768832bcbff5e9ab39ae8d1d3763bbf1e531bed98fe51de5ee84f50fb
second   x: 79be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798 private base x
third   x: bcace2e99da01887ab0102b696902325872844067f15e98da7bba04400b88fcb
even   y: 483ada7726a3c4655da4fbfc0e1108a8fd17b448a68554199c47d08ffb10d4b8 small range y private key: 1
odd   y: b7c52588d95c3b9aa25b0403f1eef75702e84bb7597aabe663b82f6f04ef2777     big range y private key: fffffffffffffffffffffffffffffffebaaedce6af48a03bbfd25e8cd0364140


 Like the a math realation bettewn first x and the second x?

 Ok unixb0y

 also if you have any intrest on working on this nonce mining website ,send me a PM

  How successful was your miner?

 also what fpga did you use and was solo or with pool?

 I got more confused by "guessing a random number" 

 anyway tink about a website that you could go on there and guess a random number, and if the number is correct you will get 100k?  (no gamble the random number will be used to mine bitcoin)

 thats another idea BTW

  not asmbling but desining one

 I'm paining to make a custom miner from scratch

(have experience with micro controlers and fpgas)

BTW thank you for your info

 if anyone reading has atempted to do so, have you succeeded?

 I get the sha256d part but how can I broadcast my hash to other the nodes?

 So mining bitcoin is baced on the SHA-256 algortiem

 is it posible to Guess a random number and do the SHA-256 and then enter the result on the bitcoin website ( witch I do'nt know the url or any thing about it but there probebley is somthing like it ) and then if the number is corect the reward will be given.

 or maybe is there a way to just solve math problems on a paper to mine bitcoin?

 If any one is looking for a trinx mountan bike send me a pm
