5btc recommendation
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

Novice first of all to know how to calculate your cost, recharge, trading, cash, there are fees. At least you can understand the K-line. There are a lot of people on the K-line. You can look at it casually and understand it. You need to be risk aware. Bitcoin is a high-risk and high profit investment. It may double overnight, or BMW may become a bicycle overnight. At the beginning, we suggest a small amount of investment
but it's hard to get bitcoin for indivial mining, so it's basically large-scale mining, and you need to cooperate with the mine pool.

(10) in the bitage, the overseas version takes a very long time to review, and it takes you a long time to pick up the coin and issue the coin. The miner's fee used to be a little higher, but now it's just a little higher. 0.5% for recharge, 1% for withdrawal, and the highest withdrawal fee in the whole universe.

But actually we all know that investment has certain risks, and if we can't grasp this degree well, we are likely to make serious losses. Especially bitcoin. Our understanding of bitcoin is not so deep, and we may not have a comprehensive and in-depth understanding of bitcoin. If we invest in bitcoin casually, we may have a bad result, and we may have a worse behavior. Bitcoin has exceeded US $52000. Why do you still suggest that we do not invest blindly? I think there are three main reasons:first, bitcoin is still unstable
in fact, as a virtual currency, since bitcoin exists in the market, it means that bitcoin will still have some instability. If you invest in bitcoin casually, it is likely to lead to a bad result and also be affected by the instability of bitcoin. This may cause us to have greater risks, which is actually unfavorable for us, and we can not allow ourselves to have a more casual behavior{ RRRRR}
