i wonder why people still want to write on this topic .The dev now only thinks about $ and not releasing his private miner.Why do you even still thank him and want to donate btc?Just donate to new devs who releases xmr and new coin algorithms
so and you are in crypto for ? Making free heat with free software (have you think about global warming how bad it is),
sorry... I just assumed you were using software to mine coins... (hence expecting to make money with softwares given freely with the hope that nobody will forgive how they get them... sorry if this sounds wrong to you...)
And yes if you use xmr algo donate to tsiv.
