[DigiSoul]

Suppose i want to make a transaction with an unknown person and i want to buy bitcoins from him .. How could i be assured that if i be sending him the money he will be giving me back bitcoins in exchange and what if he doesn't pay?? How to make this transaction WITHOUT USING ESCROW SERVICE?

The only way to be certain you will receive Bitcoins without using a trusted escrow agent is to insist on the seller sending first, though that might be a deal breaker for him.

If you do pay first and he runs with the money your recourse (if any) will depend on the payment method you used.

This is not possible without using escrow in middle, but there are also few members here in forum who have built really good trust so you may deal with them with peace in mind if they are willing to sell bitcoin for the payment methods you have cash in.

You can check currency exchange board of this forum https://bitcointalk.org/index.php?board=53.0 to find some highly trusted bitcoin seller

unknown person - WITHOUT USING ESCROW SERVICE - doesn't pay - secure tx : Actually what you are looking for exactly ? Maybe you are trying to find out any paypal similar dispute resolving services ?

Bitcoin is non-reversible, once go out of your wallet it will be gone for ever. So, secure yourself before sending. That is alone possible.

Like everyone else have said, there is no other way to secure the transaction but to use escrow. This is the only way you can secure your money. Or just avoid transactions with unknown persons that you don't trust, use some exchanger instead. Be careful, many people just want to find the way how to steel others' people money.

I don't see why you would not want to use escrow service, there are very reputable members in the forum that do it for free or for a very small fee, if the unknown person does not want to use escrow that should be a sign that maybe something is not right and you should not deal with this person.

its the matter of trust-pick a trader with good reputation and trust history
it doesn't guarantee that you won't get scammed,take e-bay as an example
but the best option is escrow nonetheless,you cannot avoid it if you want the trade and transaction to go smoothly
yes,you pay some extra but it gives you piece of mind neccessary
some of the forum members escrow at 0%,don't see why won't you try them out

transaction without exchanger and escrow is very danger
your must find trused if you want transaction without escrow
you can find in curency exchange section in bitcointalk about trusted person, but trusted in price is same in exchanger

you are buying bitcoin so you shouldn't be the one who worries since most of the money processors support some kind of charge back feature that the person paying money can use. bitcoin however does not have any charge back or what you are looking for. and the only way to be 100 sure and safe is using a legitimate service like circle or coinbase that you are sure they are not ripping you off.

[X-ray]

Don't know the reason why you seems really don't want to use escrow service and didn't intended to while it could save your money when something you didn't expect to come just coming. though there's no way to secure your transaction without using escrow service so i just can strongly recommend you to use escrow service even there's an escrow service who doesn't charge you.you're not going to pay any cents

the questions is why don't you want to use an escrow service?
any trade that involves bitcoin needs trust and without it nothing can be done, so you either trust the person you are trading with and vice versa and you do a rock paper scissor and winner sends first
or you use a third person to act as escrow so that not you nor your partner can pull a scam.

There is no other way but to use escrow to ensure that your goods will be delivered to you. Since you are just a newbie, they will be wary making transactions to you. So other party will probably require an escrow anyway.

No. Bitcoin transactions or irreversible. The only option is going to be escrow, as other mentioned.

You are talking about for examples paypals dispute/payback system? It's a total joke.
They always one-side with the paypal customer,  even if you have valid proof.
Dont fall for these tricks op, don't go first in a deal where the other party says you are secured because of the paypal system. It's not true.

I guess to have secure transactions, we must develop some good community of friends to transact with them frequently.

Forming a group with reputed members will assure secure transactions even with the bitcoin payments, I believe. This type of team formation must be done with local people like we know them personally and physically.

I guess not using escrow is not that good like what you stated that you how could you assure that if you send him the money and  he will
give you back certain bitcoin.

Very risky indeed unless he knows the person personally.Escrow is the best option here, since you are dealing with totally anonymous person.Don't be another victim of scam, be wary and cautious every time you made transaction.

[Butsuma]

you can involve a third person who is trust worthy to be the middle man

[Kevin77]

OP clearly mentioned about "no escrow". A middle man is nothing but escrow.
A perfect solution for OP must be trading only with well known people. Online friends/group still will not guarantee a secure transactions as one person may turn scammer at any time hence dealing with colleagues or neighbors or relatives will be the right solution imho.

Many people are making tricky ways to get money without working it like dealing with people and run away afterwards.
Unless you use PAYPAL where you can get back your money if you tell them that you did not get the service or item you need to have.

Without using a Trusted middle man your transaction can't be secured if you want your transaction to be secure then deal with the person face to face or buy bitcoins from a trusted bitcoin exchange website but using escrow is the best option. If the transaction is big like you are going to buy 1 bitcoin then split the transaction in 2-3 parts first buy 0.25 then buy again 0.25 and so.
And if the user doesn't pay you back in bitcoins then left negative feedback at his profile if you are buying from this forum otherwise, you cannot do anything if he scams you. You can only report it.
