What we’re doing with Bitcoin Unlimited, simplyFormatted article available on Medium here.Bitcoin has no center. It has no Board of Directors. It has no CEO, no President, no Chieftain, Sheik or Shah. Bitcoin is a decentralized network made up of voluntary participants — only loosely connected — who come together for their mutual benefit. There are users who transact in bitcoin to take advantage of its privacy and convenience, and investors who hold bitcoin hoping to profit from its price appreciation. There are node operators whose computers validate and relay the transactions made by Bitcoin users, and there are miners — a special type of node operator — whose mining farms append blocks of new transactions to the permanent blockchain ledger, rewarding themselves for this service with 12.5 newly-minted bitcoins. The fact that Bitcoin has no center—that Bitcoin is decentralized — is the very essence of its nature. It is this lack of a center that helps to ensure the integrity of Bitcoin as money. If Bitcoin had a center, users would have to trust it not to reverse or censor payments for political reasons, or reward itself unfairly with newly-created bitcoins. If Bitcoin had a center, it would be much less useful as peer-to-peer electronic cash. And there is no doubt: Bitcoin is useful as electronic cash. One measure of its usefulness is the price of a bitcoin, which has increased from $1.08 six years ago, to $993 today. A second measure of Bitcoin’s usefulness is how often it is used. The total volume of transactions processed by the Bitcoin network has likewise climbed from 1 transaction per minute six years ago to an average just shy of 3 transactions per second today. A third measure of Bitcoin’s usefulness is the number of people using it. Due to Bitcoin’s pseudonymous nature, user-base estimates are often disputed, today ranging anywhere from hundreds of thousand to tens of million. But one thing that is not disputed is that the growth of Bitcoin’s user base was a primary driver increasing both the total volume of transactions and the price of a bitcoin. Bitcoin’s lack of a center comes with a cost too: there is no conductor waiving his baton, coordinating the network participants while they play from a curated score. Even changes that are widely perceived as positive are difficult to roll out, as doing so involves communication and cooperation between the loosely-connected participants who make up the Bitcoin network. The most pertinent example of a need for change is the “1 MB block size limit.” In 2010, Satoshi Nakamoto added a protocol rule that limited the volume of transactions committed to the blockchain to roughly 3 per second (3 transactions per second typically fills blocks up to the 1 MB limit). When the limit was added, it was 800 times greater than the natural transaction volume, and so the limit did not constrain the natural growth of the system (it served only as an anti-spam measure). But today, the network is “maxed out,” regularly hitting this limit, and no longer free to grow how it did during the first 7 years of its history. Fig. 1. Transaction volume on the Bitcoin network is now constrained by the 1 MB block size limit enforced by approximately 90% of network nodes. If the block size limit were raised, the transaction volume wouldn’t immediately fill it, but would rather continue to grow similar to how it grew before hitting the limit. How might we increase this limit, if Bitcoin has no center that can do it for us? To answer this question, we must first understand who it is that is enforcing the block size limit. So who is it? Why can’t Bitcoin users make more than the 3 transactions per second on average today? The reason is related to the fact that when a payment is sent between two users, it doesn’t actually go directly from User A to User B; instead it is relayed to, and approved by, every node on the network. There are approximately 6000 accessible nodes, or assuming bitcoin has 5 million users, about 1 node for every 800 users. When a miner finds a new block of transactions to add to the blockchain, each node checks the size of that block. If the block is larger than 1 MB (i.e., if it contains more than approximately 3 transactions per second worth of data), 9 out of 10 nodes today would reject that block as being invalid. No miner would risk intentionally producing a block larger than 1 MB because he knows that the network as a whole would reject it and his 12.5 BTC reward would be lost. And so even though miners may want to process more transactions per second, they don’t because effectively they can’t — the other nodes won’t let them. We see then that to increase the limit — to allow miners to process more than 3 transactions per second —it is the people operating these nodes who must take action. Node operators must convincingly communicate to the miners that they are ready and willing to accept larger blocks. This is especially true for economically-significant nodes such as those running Bitcoin exchanges, payment processors, and web wallets. What we’re trying to do with Bitcoin Unlimited is give node operators a flexible set of tools to allow them to do this. Very simply: 1. Bitcoin Unlimited allows a node operator to quickly and easily change his node’s block size limit. 2. Bitcoin Unlimited allows a miner to quickly and easily change the maximum size of blocks his node will produce. 3. Bitcoin Unlimited helps node operators and miners signal their block size preferences to the rest of the network. Today, approximately 1 in every 10 network nodes is running Bitcoin Unlimited, with a median block size limit of 16 MB. As more and more node operators take similar initiatives and raise their node’s block size limits, miners become more and more tempted to produce larger blocks that contain more transactions. At some point — when miners are comfortable that a sizeable majority of the network is ready and willing to accept larger blocks — a miner will produce one, it will be accepted into the permanent blockchain ledger, and Bitcoin will be free to continue growing. What we’re doing with Bitcoin Unlimited is that simple. The price should rise significantly next weeks.

Alguém postou lá na área da especulação, eu salvei a imagem mas não o post. Desde 2015 existe um certo padrão nos preços, a cada 7 ou 9 meses acontece um novo pico de preço que é cerca de 60% ou 70% maior do que o pico anterior, e depois ocorre um dump pra um nível de preço um pouco menor do que o do pico anterior. Acho que vendo a imagem dá pra entender um pouco melhor: Se isso acontecer de novo uma vez, então o máximo de preço vai estar entre $1760 e $1870 lá por julho-setembro, e então o preço vai cair para algum lugar entre $900 - 1050 Se acontecer de novo duas vezes, então o preço vai para uns $2900-$3000, depois o dump vai para uns $1500 talvez, daqui a uns 14-18 meses Se alguém comprar um bitcoin hoje a uns $1000 dólares/btc, lá por agosto iria ter $1800, e se vender perto da baixa iria conseguir uns 1.7 bitcoins mais ou menos. E na próxima o resultado iria ser uns $5k na alta e pelo menos 3 bitcoins caso se venda perto da baixa Se considerar o valor de 4000 reais como o máximo do começo de ano, de acordo com o mercado Bitcoin, o potencial para daqui uns 18 meses no máximo seria de 6400 reais/btc lá por agosto e uns 10200/btc daqui a 14-18 meses, com 1.7 Bitcoin isso seria equivalente a uns 17400 de capital total, e considerando os 3 BTC pós dump, caso o preço um dia volte lá pelos 10k/BTC, equivaleria a 30k reais de patrimônio total, por bitcoin TLDR: será que dá pra transformar 3000 reais em 17k-30k reais em dois anos mais ou menos comprando e vendendo Bitcoin no momento certo, sem esperar por uma bolha no estilo de 2013? opininem Dia 11 de março teremos uma boa ou má notícia pro Bitcoin. Creio que atingiremos um novo pico até lá ou uma descida brusca, corrigindo e mantendo-se entre 900 e 1000 dólares.

You offer good rewards, but I don't know how you will be able to pay up to 0.00288 BTC daily to players on tier 5.
And how can I earn experience on your site?
You gain experience when collecting. You can also increase the gain XP with Multiplier item XP. Looks good will have a look at it, thanks
Thanks also! my friend was signup under me, why i didn't get the reward?

I bring UPDATES: The referenced system now pays 5% per collection . The return on investment is 100% in 30 Days. Wow, double money in 30 days, it's a very good offer. 3.33% daily profit. But how can you pay this amount and have profit at same time? I think Ads income isn't sufficient. Even you use Adsense, I think the ads income doesn't cover the expenses. Hi friend, remember that we have only one user to generate income and not only a method, we have enough to cover our expenses. Any other questions I'm here to satiate them. Can you clearly state the real source of sustainable income? "The return on investment is 100% in 30 Days" is not "Micro Earnings", but it IS probably a ponzi scheme. You're being too hasty. First the payment is the minimum 50k satoshis. You make this in probably 5 days. yes, it is micro earning. And If you didn't see, there's a fee with the withdrawls too. So take it easy.

Your rewards is really very low. 0.5 dogecoin means 20 satoshi at current rates. I would understan your rewards if thr timer would be 1 minute, but it's 3 hours. You must increase rewards and decrease timer if you want to get visitors, because now I can say it's not worth to use your faucet.
Thanks!
