why 74k unconfirmed transaction ?

[Spendulus]

is bitcoin network under attack ?

or its getting really popular ?

idk when was the last time i saw 74k unconfiremed transactions.

ref: https://blockchain.info/unconfirmed-transactions

Understanding the 74k, not guessing, can only be achieved by looking at two statistical measures.

For example, if 74k people got new Coinbase accounts yesterday, and there were 74k unconfirmed transactions, nobody would think anything of it.

Similar, if 150k transactions with tiny fees and 74k unconfirmed transactions, there's the answer.

But just the 74k unconfirmed transaction number, could be anything.

Bitcoin under attack? Nope unless someone has really had a grave grudge on satoshi but I doubt one would spend a lot of time in putting down a currency that is hard to attack, vectors will find it difficult to permanently shut down its system. As for the number two statement regarding the decrease in the number of miners technically its possible due to the volume of competition in mining, also it difficult to caught with the competition in mining due to the electricity consumption and its very time consuming and not to mention it really requires a lot of expense to buy a good mining equipment.

Its just the speed of the network and amount of transactions that need to be processed.

what happens if your coins are unconfirmed when the fork happens?

Since bitcoin gains more value, unconfirmed transaction increase as well, seems like there is a connection between all of this network obviously.
Whenever bitcoin price rise up significantly within hours, people tend to transfer their bitcoin from web wallets or cold storage into exchanges in order to extract profits before its price fall down, which create a spike of transactions waiting to be processed by miners.  I'm not sure if some people spam transactions to delay others transactions, but they will lose bitcoin in form of "fees" due to we have to pay higher fees to be included into next block. But, bitcoin network seems diminish faster after segwit activated 2 months ago.

They are unconfirmed but that's not forever. They're been processed by miners at the same time by miners around the world and send it to the ledgers and make sure all ledgers have the same records. There are too many Bitcoin transactions in every second. The transaction execution is indeed really fast but due to thousands of people are using Bitcoin as payment or sending to other people at the same time so the result would be pending transactions while waiting for the ledger to complete.

Meh... not a problem.
It goes down eventually. There have been even more than 74k.. Like a user said, 150k.

what happens if your coins are unconfirmed when the fork happens? 

When the fork will happen it will create a copy of the current chain only with confirmed transactions, it won't copy the mempool.

If your transaction is not confirmed till the split it will not get confirmed in the new chain ever, it's going to be like you never sent it.
It might get confirmed in the old chain after the split but the new one will have no clue about it.

So if you plan on buying btc right after the split you might end up with only btc and not s2x coins.
