Please read the stickies.  No one is going to loan bitcoins without a collateral to a newbie with 1 post who just registered a hour ago.  Those who do won't be expecting their bitcoins back.

Contact their support.  Since you can't rescan in bc.i there's not much you can do.

Yes, you should call them again.  Although users' reviews about them are mostly positive, it looks like they're quite new.  Hopefully you didn't get scammed.

They are obviously lying or just wrong.  If they're right you'd find that transaction hash in block explorers and coins in your wallet.  You got that transaction hash from their site, right?  How much did you send?

Contact triv.co.id support.  It's most likely a problem from their end.

If you lost your wallet.dat and didn't keep a backup in any form then your bitcoins are lost.
Bitcoin core and most desktop wallets doesn't use email btw.  You might be using some other wallet.  If that's the case then create a new thread about it to avoid hijacking this one.

Why are you asking how to choose backup method when you already know all of them?  Just pick whichever your prefer.
Generally the seed is all you need to restore your wallet, so just write it down on something and make sure you never lose it.
Wallet file will require you to save it in USB/PC which can be compromised by malware.
Private key exporting shouldn't be used as long term backup because you're not exporting all the possible private keys of your seed.

You can contact Quickseller or macbook-air or some other miners and ask them to help you get that transaction confirmed.  They will probably ask for a small payment.

Set the fee to the recommended amount.  Which is 90 satoshi per byte or 0.0009 per KB (shown on the site I linked).

However, the last time I used blockchain.info the site doesn't even show the fee per kb, only the recommended amount.  If it's still the same then you're pretty much blind.

Edit:
Yup, it's still the same.  All you can do is blindly increasing the fee or get another wallet software that shows the fee per KB (I recommend electrum.

The fee is lower than the recommended fee of 90 satoshi per byte.  According to https://bitcoinfees.21.co/ a transaction with 57 satoshi/byte fee will take anywhere from 15 to 480 minutes to confirm.

Indonesian board is that way (Or maybe Philiphines?).  Ask there instead of posting a machine translated message with untranslated leftovers.

Signature campaigns are services that pays you to make posts while wearing their signatures.

So the competitor have to pay 0.001 to get the encrytped .dmg file which may or may not be real?  

Investor based games section is meant for sites that requires user to invest in order to participate, but it was created because the high number of threads about obvious ponzi sites.
In bitcointalk scams aren't moderated, and creating a sub-board called "scam services" and moving threads there counts as moderating scams.

There was some bitcoindoubler sites that pays, but they still scammed in the end.

Don't take that as me siding with those ponzi sites, btw.  I'm just being honest.

When using blockchain.info or any other web wallets you're trusting them to keep your coins for you.  It doesn't matter if they say they don't share unencrypted private keys to their server because that can change anytime they wish to change it.  You're also relying on them to keep their website accessible to you whenever you need to use your coins and fix some problems that can be fixed by yourself if you fully control the wallet.

You can't view the private keys of or sign a message with a non-imported addresses with blockchain.info (I'm not sure if that's changed) and it doesn't use any less fee than any other wallet.  Fees can be set manually if you wish to, btw.

In short, yes, wallets like electrum which is pretty much the opposite of what I said above (except the fees part) are more secure.

Edit:

They're not that complicated.  I've used a lot of wallets including blockchain.info and they're pretty much the same only with added or removed features.
If you think any of the features are unnecessary then simply don't use them, that shouldn't stop you if you want a more secure wallet.

You can just hover your mouse pointer over the change addresses option or click the coin selection and it'll give you very good explanations on what those options are.

Looks like both transactions have been dropped already.  You can lock the thread if you don't have any more problem, OP.

That's used for verifying, not signing.  Signing will generate signature instead.

That's an address, not a transaction.  And that address only have confirmed transactions that will never be dropped because they're already part of the blockchain.

If you're having problems with unable to spend from your blockchain.info wallet, contact their support.  We can't do anything.

There's no such thing as "automatically double spend" for big transactions.

Edit:

Blockchain.info is not showing that transaction in the transaction history of the address posted.

That transaction will be dropped within 72 hours provided that no one else rebroadcast it and the unconfirmed input which is the source of the double spend problem.

Transaction ID?
Try switching servers manually till you find one that doesn't have the transaction and resend.  If you can't find it then wait a little longer before trying again.

If there is a censorship that thread would've been moved to the trashcan.  From what I see that thread got locked because of the trolling and also because replies pretty much goes in a circle since it started (User A asking if it's true or something similar, User B telling it's not true, rawdog trolling, Someone else counters rawdog with a little techy post, rawdog trolls back, and on and on).


It did look like that at first, actually.  But then the constant trolling and swearing kinda blew all of it.
