Yes, there is nothing wrong with the program.
But note that mining on PCs ended in 2013. Bitminter client is now only
useful for old USB-based ASICs. Those ASICs are no longer profitable though.
You probably do not want to use Bitminter client or old unprofitable
ASIC hardware. Modern ASIC hardware is stand-alone and do not need a PC
You need to buy modern bitcoin ASIC mining hardware. Mining one bitcoin with just a PC now takes millions of years (not a
joke). You should get at least a 1 TH/s or faster ASIC machine to start
a small mining-at-home operation. Popular now are Antminer S-series fromhttps://bitmaintech.com
- for a list of ASICs seehttps://en.bitcoin.it/wiki/Mining_hardware_comparison
bitmaintech.com sells a new machine but it may be a bit expensive for
starting out. You can find used Antminer S-model miners or machines from
KnCMiner, Spondoolies and others at places like ebay.com. If you buy a
different miner you can still use the miner and power supply from
bitmaintech.com as a reference for a decent price per GH/s. If a machine
and power supply from there costs 0.30 USD per GH/s then you don't want
to pay much more than that elsewhere.
When you get your ASIC machine, connect it to the pool at
stratum+tcp://mint.bitminter.com:3333 and as user name put your
Bitminter user name, an underscore, then a worker name, e.g.
DrHaribo_asic3. Send X, 123, or whatever you want as password - our
server won't care.
