Post TXid, at any rate it must've been low fees

(Not my bitcoin address/transaction) https://blockchain.info/tx/8f661a6010a6e9664916c9e76bae99f4281f927ee7ce1d7546a708aab8118e7a

There is a DOS attack against the blockchain going on right now. It's causing transactions to take longer than usual to confirm.

In order to pull of the attack, the attacker has to pay a higher than average transaction fee. They will eventually run out of money and the attack will stop, but in the meantime you can send your transactions with higher fees to make sure that your transactions get confirmed instead of the attacker's (this will have the added benefit of forcing the attacker to spend through their bitcoins even faster to maintain the attack).

Another attack...last 6 blocks (edit: and counting) have been hit.

Example: #385910 with 19125 fake sigOps. The block is only 200KB despite a 5MB backlog (according to tradeblock). It seems this attack is very effective.

Edit:
#385911 unaffected (enough high-fee legit txs)
#385912 = 18990 fake sigOps, 280KB.
#385913 = 18945 fake sigOps, 281KB.
#385914 = 17325 fake sigOps, 470KB.
...etc.

I think it's not only that. The last days the bitcoin price was relatively volatile which mostly leads to a lot more transactions which then leads to full blocks and legit transactions not confirming. I found this website being valuable for checking the status: http://statoshi.info/dashboard/db/transactions

So how more people get into btc, more transactions will come and when blocks are full, u just wait till the other block? So sending btc will take longer in the future? Even if u pay more fee, if everyone is going to pay more, then it is useless?

You can wait for the other block but in the meanwhile already new transactions came to the pool that are worth more than 1MB. So it is not said your transaction will be included at all.

And yes that will get worse as long as the limit is not raised. Though there are some people, unfortunately a lot bitcoin developers too, that want it that way. They want to let people use the lightning network and they want higher fees. It's completely nuts to force bitcoins into such limits when you go deeper in that topic.

Though i'm not so very much concerned. At one point in time bitcoiners will raise their voice in favor of raising the blocksize limit. Developers will follow or have to leave the coding work to other devs.
