If somehow, you’ve only heard of one cryptocurrency, it’s probably Bitcoin. It is the biggest cryptocurrency — it currently has a 40%i share in the total cryptocurrency market cap! It is the oldest cryptocurrency and it still dominates in the market. So, if Bitcoin continues to increase like it did in 2017, then investing in Bitcoin might be a good idea for 2018.
The trading strategy used is bollinger bands. (You can create bollinger bands on graphs in poloniex). The strategy is to buy when price touches lower bollinger band and sell when the price is above your bought price and also hits high bollinger band. If the price goes down and again touches lower bollinger band then invest another 25% of total investment assigned for a currency.
Ethereum ETH, Monero XMR, Factom FCT, DASH, are all leading coins and traded the most volume daily. You should follow the coin’s chart and identify low and stable periods. Such periods are likely to be a consolidation period by the whales, and when the right time comes, accompanied by a good press release of the project, the pump will start and they will sell in profit.
One of the most powerful tools made available by the Blockfolio app is the price tracking functionality it offers. The Blockfolio app is able to deliver running price updates via push notifications directly to a smartphone as soon as a currency reaches a predetermined level, increasing reaction speed for high priority buying and selling actions when prices reach a specific threshold.

Use small buy-ins, and don’t margin trade or short unless you know your stuff. The smaller your bet is compared to your total investable funds, the less risk you are taking on every bet (one of many insanely important things we are covering here). Putting it all on black is tempting, but then if it comes up red, you have nothing left to invest. Live to fight another day by learning to manage your buy-in size. As a rule of thumb invest 1% or less per buy-in (yes, that small, really; losing 100% of 1% leaves you with 99%, losing 1% of 100% leaves you with 99%. Small bids offer the same bet, but with way less risk). Put reward aside and practice risk management and capital preservation until you are very experienced (and thus, by logical extension: don’t margin trade or short unless you know what you are doing, as those leveraged bets magnify your risk by their very nature). See Kelly criterion.

This is not a get rich quick scheme. While returns can be good at times, I have seen periods of stagnation, five +30% market dips and a bear market. Whenever you enter the market, it could be on the rise, in a drop or be stagnating. I have also had days and weeks where I have seen a significant decline in my portfolio. I can't predict what the market will do when you enter. Please invest for the long term. This is much more volatile and risky than the stock market.
You need a trading plan. You can basically consider it to be a blueprint for success. Your plan has to take everything that you can into account like entry and exit of money, risk management, time frame and even position sizing. Without a plan and too much emotion, you will be gambling instead of trading and you will never know how to improve your skills to become better.
Always learn from your mistakes. Never accept a total loss. Always evaluate the situation and try to figure out why it happened. Take that experience as an asset for your next move, which will be better because you are know more now than you knew before. We all start off as amateurs, and we have all lost money throughout out trading experience. In his first month of trading, Miles went from $1,000 to $300. I’ve lost a lot by selling at losses inspired by fear. No one is perfect, no one wins every single trade. Don’t let the losses discourage you, because the reality is they’re making you better trader if you choose to learn from them.
