paypal is an easily reversible payment method, so unless you agree to have the trade take 180 days such that the paypal funds no longer become reversible, you should find another form of payment. generally though, a simple deal for a digital item can take minutes if good communication is practiced by all 3 parties:
I would say "best" is subjective, but to each their own.

im going to assume that you are purchasing an account of some sort (likely a forum account) using paypal; i would suggest somehow turning that paypal money into bitcoin first to ensure the funds are safefor the other party, but that may be hard to do as people will not deal with newbies and paypal. the fees are high but virwox may be a possibility.

nothing wrong, just thought it looked odd is all.

that is only multibitHD, the earlier versions of multibit do not have this fee, which if you ask me, is pretty negligible. iirc its an additional 1000 satoshi to every transaction that goes directly to the developers, which is more than deserved considering the work they do and put into maintaining the wallet. if you download the earlier versions of multibit (0.5.18 or before), those versions do not have the fee included. no need to be stingy over a fraction of a penny.

why do you have the money to lend out when you were asking for a loan quite recently? https://bitcointalk.org/index.php?topic=1162155.msg12244553#new

you should point out why he might want to use a light wallet; bitcoin core requires that you have the full blockchain downloaded, which i believe is well over 30 GB at this point. in addition, the core client is rather resource intensive, or it was last time i ran it. if youre looking to use bitcoin just for daily spends or keeping a few bucks on there,a light wallet might be better for you as they only require you have the client downloaded, and your wallet will sync with servers that have the whole blockchain downloaded. in addition to the two wallets linked above, electrum is a fantastic light wallet as well, and has cold storage capabilities built in.

the currency exchange section on the forum is also a place that you can buy bitcoin. however, there are restrictions on what is accepted there, especially for newbie members who are just getting into bitcoin. members will only deal with newbies if the payment method they offer is irreversible in every sense of the word (OKPay, western union after money is picked up).

should a newbie choose to accept those conditions and pay fees associated with the trade, they wont even have to go through a verification process as an exchange such as coinbase or circle might require you to. however, people over there arent too keen on dealing with newbies, so it might be hard to even find a seller. however, if going first with a trusted seller, there wouldnt be any escrow fees involved, and there are plenty of free escrow services should the user want to use escrow for the deal.

you should list the sites you own here then, and give the relevant statistics for each site that will help to determine their value to the lender (traffic, charts of income per day/week/month, alexa ratings, etc). you should also be aware that you will have to hand your collateral to an escrow service prior to receiving the funds for your loan to guarantee that the lender can take possession of the collateral should you default on the loan.

also, be aware that the collateral value should be greater than the value of the loan.

pretty much, since youre relying solely on the borrower's honestly to have the loan repaid at this point, and when money  is a factor on the internet, honesty is rather scarce. i also checked back on my btcjam account a bit back, and to my surprise, a 0.02  loan got repaid, which i really did not expect. turns out the borrower got doxxed. its quite sad that thats what it takes for someone to repay a few hundred dollars.

collateral sounds like something that would vastly improve the lenders' experience on btcjam, if they could implement an option for a borrower to provide some sort of collateral, and set up a system to hold such collateral, i could see btcjam becoming a real service. would be quite difficult though, since i would expect most collateral to be physical.

this point is why the lenders who accept altcoins only choose to accept stable altcoins as collateral, and ask that at least 115%+ of the loan value is given as collateral. a loaner who doesnt really know better is vulnerable to being scammed this way i would imagine. i dont often see altcoins used as collateral on here though, at least not nearly as often as forum accounts are used.

when you say api, first thing that comes to my mind is moneypot, am i right? if so, i can direct you to a trusted member that runs a moneypot app and can help you set this up.

not too hard if you give out no information whatsoever that could possibly link you back to your real identity, but given a case like yours, where you do trades with paypal, bank transfer, whatever else, it can get a tad difficult to say the least.

if vortex is just a chat moderator i dont see why he would be obligated to join the campaign. he's free to do what he chooses.

loads of free information available on the internet, you shouldnt need anyone else to help you if the script is working and secure. it wouldnt hurt to start learning some coding in case you need to apply some fixes in the future and dont want to pay someone. youre going to need to download some libraries onto the vps though.

fixed my sig, seeing as im the only one that was accepted to the campaign. i find it odd though, i thought people would be jumping on this given the no post count restriction on this campaign.

can i assume that the dice script is in php?

im assuming you only have the script on hand as you dont mention anything else in the op, next step would be to get a domain name purchased as well as a vps to host your website. theres plenty of guides available and you could do this all by yourself if you dedicate an hour to looking up how to set everything up.

this is entirely true, there is no reason for a casino to give you a way to win or even a slight edge to win because it will not benefit them; even the rakeback programs some casinos offer are there to encourage you to gamble more, they will in no way guarantee that you will come out ahead. just take a loom at betterbets' program; i believe it was something like .2% of your bets back at a certain amount wagered; in a perfect world, you would still be expected to lose out given a house edge of 1%.

unfortunately, thats pretty true, just take a look at this one that claims to have been scammed by a partner, and is now asking for 20 btc to "save the project." https://bitcointalk.org/index.php?topic=1067965.msg12229800#msg12229800
 however, if the service can provide enough proof that the legitimacy of their operation is undeniable, then it might not be that bad of an idea to invest, if youre ok with an ROI that could take months.

i think the panic can be attributed (partially) to the XT vs Core debate doing on right now, which is causing a lot of FUD about "the death of bitcoin" and whatnot. yes, its true that bitcoin has sprung back up, and will likely do so again, but the addition of this debate adds the uncertainty that XT may take over everything. but yeah, the panic doesnt really help anything, best to just wait and see what happens.

most of the dice games that are advertised on the gambling section do not resemble a dice roll at all, the "rolls" from those games can have up to 10000 values (0 to 99.99 inclusive). i believe its jjust callled "dice" because the term would describe it as a game of pure chance (assuming the game is provably fair) with nothing to complicate the game.
