Bitcoin — is a pioneer crypto advertising network. It offers ethical privacy-aware CPA, CPD, CPM ads and accepts over 20 major crypto-currencies, including Bitcoin. Bitcoin (Bitcoin) is one of the world's first digital decentralized currencies, working on the Proof-of-Work algorithm (Proof of Work). All transactions of the Bitcoin network are recorded in blocks thanks to miners who donate the power of their computer to support the network, information about transactions is stored on the computers of the network participants. Simply put, bitcoin is a digital coin that you can send via the Internet anywhere in the world for a couple of dollars in commission. They cannot be faked, taken away, stolen or frozen on your account. Since they are not controlled by banks and states. Earn Bitcoin and other cryptocurrencies through mining, cryptocurrency deposits, staking and trading on the exchange. Mining, as I wrote above, is the support of the network and the implementation of transactions by miners. Miners are rewarded for maintaining the network, in the form of Bitcoins or other cryptocurrency. For mining, they use powerful computers, specialized mining farms made from video cards of the latest model and ASIC miners (special computers). Staking is the support of a network of cryptocurrencies operating on the Proof-of-Stake algorithm (Proof of Stake). Instead of conventional mining, using computers, participants create new blocks with transactions in proportion to their share of ownership of a digital asset. Simply put, for staking, it is enough to own a certain cryptocurrency to receive a reward. Cryptocurrency deposits can be used on specialized platforms. The yield of such deposits can reach up to 15% per annum, and deposits can be made for a period of one day. Trading on the stock exchange is essentially a common speculation on the price difference and its volatility. To trade on a cryptocurrency exchange, you need to have an initial deposit in order to make transactions on all trading pairs. Income from trading can reach hundreds of percent per month, but this is the most risky type of income among the indicated. For those who want to buy or start mining bitcoin, you need to use specialized platforms - exchanges. According to the statistics of the Coinmarketcap website (the top foreign site for cryptocurrencies), there are currently more than 300 specialized sites (crypto exchanges).
