i have a few more questions if you guys don't mind.

Couldn't understand yet the payment system, the altcoins are auto-exchanged in bitcoin (in my case) automatically?Then converted and transferred to my wallet?If yes, when is the transfer made?
And another question, how can i check my daily income and my btc income?

thx and sorry for the newb questions

The difficulty dropped by a huuuuuuge amount, I don't know why.

Edit: It seems like SC forked at block 135000, lowering the difficulty of the coin
Edit2: It's only temporary because there's a bug in the fork, requiring yet another hard fork:

1. Blocks will first speed up quite a bit. Then they will slow down to a long term 30 minute block time until we do another hardfork to fix this.
2. Other than a week of really fast blocks (tomorrow the block time could drop as low as 2-3 seconds for an hour or so), there's not going to be much disruption to the network. We can safely ride this out, don't need rollbacks, don't need an emergency call-everyone-you-know hardfork.

is it safe to mine sia ? we don't lose the current mined coins right ?

Backup pools are located in the folder called 'pools'. Add/remove at will.

All standard Bitcoin addresses work. BitPay and Coinbase work plus many more.

You don't need to see things for it to work. If you are a trader who wants to know all the exchange rates then turn auto exchange off and send it to an exchange yourself.
