This is a typical recommendation coming from stock and Forex markets. There is a probability of a strong and significant price wave when rumors appear. Those who buy on rumors have greater risks as there are still no facts to prove them. However, they also have better profit opportunities as trends are in their initial phases in moments when such rumors appear.
That bold green candle yells at you “you are the only one not holding me”. At exactly this point you will notice lame people flooding the Crypto forums and the exchanges’ Troll boxes to talk about this pump. But what do we do now? Very simple, Keep moving forward. True, it’s possible that many may have caught the rise ahead of us and it can continue raising, but bare in mind that the whales (as mentioned above) are just waiting for small buyers on the way up to sell them the coins they bought in cheaper prices. Prices are now high and it’s clear that the current coin holders only consist of those little fish. Needless to say, the next step is usually the bright red candle which sells through the whole order book.
The cryptocurrency market is insanely volatile in 2018. You can make a fortune in a moment and lose it in the next whether you trade Bitcoin, another coin, or the GBTC Bitcoin trust. Consider mitigating risks, hedging, and not “going long” with all your investable funds. TIP: If you trade only the top coins by market cap (that is coins like Bitcoin Ethereum), or GBTC, then the chances of losing everything overnight are slim (not impossible, but slim). Other cryptocurrencies are riskier (but can offer quick gains on a good day).
Always pay attention to Bitcoin. Most altcoins (every cryptocurrency except Bitcoin) are pegged more closely to Bitcoin than Asian currencies were to the USD during the Asian Financial Crisis. If Bitcoin price pump drastically, altcoins price can go down as people try to exit altcoins to ride the BTC profits; inversely, if Bitcoin prices dump drastically, altcoin prices can go down, too, as people exit altcoins to exchange back into fiat. The best times for altcoin growth appear when Bitcoin shows organic growth or decline, or remains stagnant in price.
