Do you think that Bitcointalk is a good way to get knowledge and information about Bitcoins?? because Bitcointalk is very useful for me to get information about Bitcoin.
If you know how to filter all the spam and useless comments, then yes this forum is still a good way to get information and learn more about Bitcoins and cryptocurrencies. It will need a lot of careful reading and sorting.
The best informatoin can be obtained from the mining section, both for the bitcoin and the altcoin.
