#比特币数字币 has been in the currency circle for nearly ten years, has made and lost, ICO, Dogecoin, and mining have all been tried, and have gone through three rounds of bulls and bears. After reviewing countless operations, I found that there is only one way to really make a stable profit - the underlying logic that is so simple that everyone understands: buy in a bear market, sell in a bull market, and that's it. The bull-bear cycle is clear: a bull market typically lasts from 6 months to 1 year, a bear market lasts 1-2 years, and a full cycle lasts 3-4 years. Catch the rules, earn 50%+ gains in every bull run, and easily outperform money, stocks, and funds – it's not speculation, it's the iron law of the market. The practical rule is divided into five steps: Only dormant layouts in bear markets Be patient and aim at the bottom of the bear market (marked by the fact that no one cares about Bitcoin and the currency circle is silent) to enter the market in batches. This phase may last more than 1 year, but it is a golden period for picking up chips - you don't have to buy at the lowest point, and it is safer to open positions in batches. Only mainstream coins are selected for heavy positions BTC, ETH: the core of the currency circle forever, buy in the bear market, sell in the bull market, 50%+ increase is the basic market, the first choice for large funds. Platform currency: such as BNB, which is deeply bound to the exchange and has strong resistance to decline. Strong public chains: such as SOL and AVAX, the technology is solid, and the bull market has enough momentum to keep up. Infrastructure coins: such as MATIC, have a wide range of ecological applications and clear long-term value. Be wary of consensus coins: such as Dogecoin and SHIB, there is no substantial application support, it all depends on speculation, and it can only be entertained with a very small position, and do not take heavy positions. Iron Law: Altcoins are essentially "leek cutting tools", and coins that have skyrocketed in the bull market may be reset to zero in the next round. Betting on copycats without insider information is equivalent to gambling. Take profit decisively in the middle of a bull market Initial stage: BTC led the rally, ETH followed, mainstream coins slowly rose, and a few altcoins moved. Medium-term: BTC and ETH fluctuated and climbed, mainstream coins broke out in full swing, and altcoins began to follow suit. Later stage: BTC falls first, ETH may sprint last, and altcoins rise wildly (several times or even hundreds of times). Epilogue: BTC plunged thousands of points, rebounded briefly and then fell again, ending the bull market. At this time, be sure to stop the loss and do not have illusions, otherwise the principal will be lost. Rejection of bull gambling seizures In the middle and late stages of the bull market, altcoins are flying around, but following up at this time is tantamount to taking a fire from the fire: Altcoin gimmicks are full of gimmicks and sharp rally, but there is no fundamental support, and the bear market will be cut in half and returned to zero. If you really have itchy hands, gamble with no more than 10% of your funds, and don't increase your position even if you make a profit - one heavy position mistake is enough to wipe out all your gains. Principal safety above all else When you accidentally get covered, decisively cut the meat to protect the principal. Stop loss before the bear market crash, with a maximum loss of 50%; If you carry it to the end, you may end up losing all your money. After cashing out in the bull market, wait patiently for the bottom of the next bear market, don't buy the bottom on the mountainside, and don't chase altcoins with profits. Finally, I would like to give you a word of advice: There is never a shortage of opportunities in the currency circle, what is lacking is the rationality to restrain greed. Follow the market cycle, don't be confused by short-term fluctuations - save coins in the bear market, sell coins in the bull market, keep the principal, stay away from gambling, in order to survive to the end in this cruel market.
