In every game, there is a big shark who is waiting to take it all and leave the poor more poorer. In crypto, because of its high volatility, even the masters in the game will find themselves down sometimes but the only thing that differentiate masters of the game and newbies is strategy and how to recover from losses.
As a once upon a time newbie myself, I once experienced serial heavy losses and I learnt only one big lesson from that. ALWAYS TAKE A SMALL BREAK AFTER A BIG LOSS or A MAJOR GAIN. This rule is used by most successful investors and you will all recall how many guys died paupers after winning gambles. WHY?, they tried their luck with all their winnings and lost it all.
Never invest using social media signals as they are part of the pump and dump crew who will leave you with less investment in no time. Always do you homework before you trade, understand the coin you want to invest in, more so, have an understanding of the whitepaper behind the whole project and analyses how and what problem is the project solving. Most of these projects are just there to raise some BTCs and Ethers and boom, the whole team is nowhere to be found.
And one more thing, John McAfee is paid some good BTC/ETH for his signals for each coin that he recommends so BE CAREFUL on who you follow. Best of all FOLLOW YOUR SIXTH SENSE
