My congrats. Do you know the minimal requirements for profitable staking in respect of hardware? My wallet is on outdated notebook with Mobile Intel Pentium B950 and 4 Gb of RAM and I'm in doubt about its ability to stake.
Until Precomputed Zerocoin Spend is out (planned for next wallet release), it definitely helps to have a CPU with powerful single-core performance to reduce time to compute Zerocoin stake/spend.
After Precompute is out, CPU won't matter that much but it is still going to be beneficial to have decent single-core performance.
