Ok hope it's ok to post here but I have quickly visited all the sites and put the minimums/ fees and some other relevant info for noobs and small players in another list here:
Note that about half of the sites will absorb amounts sent below the minimum, yet don't list the minimum on the main page.
BITWHISK
0.5% fee + miners fee rate in sat/B
interface implies you can send small amounts.
however it also mentions that dust will be considered a donation
not sure what the minimum would be, especially when the fee is sat/byte
BITMIXcoin.io
0.01 minimum, it says please do not mix less than this
there is no indication however what will happen if you try
minimum mix fee 1% + 0.0005 per forwarding address
says they offer escrow on the forum cant see it on the site just now though
COINMIXER.se
random service fee 1-3 % and address fee 0.0001 BTC per output
interface wont accept amounts smaller than .001
see elsewhere on this forum for info about these sites
BITCLOAK
smallest amount seems to be 0.01,
unlike many of the mixers they will not accept smaller amounts
BitCloak fee is randomized for every order and is set around 2%. There is also a network fee of 0.0004 Bitcoins for each payout address
BITBLENDER
Minimum for quickmix is 0.01 BTC after fees (clearly labelled)
doesnt say what the fees are though on the site
a long running service but has apparently had some hiccups here and there
GHOST MIXER
fees 1-3% transaction .00005btc
minimum deposit 0.01btc, clearly labelled at the input
CRYPTOMIXER.io
minimum transaction size: 0.001BTC, smaller transactions considered donations
minimum fee is 0.5% plus 0.0005BTC
CHIPMIXER.com
minimum transaction size: 0.004BTC
pay as you like but smallest option is 0.001BTC (?)
smallest chip is 0.001BTC, apparently rounded down and leftovers absorbed as a donation(?)
BESTMIXER.io
minimum Bitcoin: 0.001 BTC
"Smaller amounts will be considered as donations and will not be refunded if sent to our wallet"
fees appear to be only 0.5%(?)
BITMIX.biz
our mixing fee is 0.4-4% (you can set it manually) and address fee:
Bitcoin: 0.001 per output address
minimal amount of Bitcoin for mixing is 0.007 per output address and maximal 1000.
Only transactions in this range will be accepted. Amounts below the minimal will be considered as donations
PRIVCOIN.io
Bitcoin our minimum fee is 0.8% plus 0.0005 BTC per forwarding address
smallest bitcoin: 0.005 BTC
Smaller amounts will be considered donations and not returned
BLENDER.io
minimum transaction size: 0.01BTC, smaller transactions considered donations
Our fees range from 0.5% to 3% for each operation, plus extra 0.0001 BTC
SMARTMIX
"We take a 0.5% service fee per transaction plus a fee of 0.0001 BTC per payout address as transaction fee."
Amounts smaller than 0.001 BTC are not profitable for us to mix. Therefore we consider smaller amounts sent to us as donations.
also note: some scam warnings/negative posts on this forum
ok there you go, feel free to correct anything that is wrong, trying to be helpful here
