Investing isn’t poker or rather it should not be a gambling game. If you go all in with investing in an asset or two, you are almost certain to lose everything, it is just a law of probabilities. Diversify. Do not believe anyone who tells you otherwise, ever. Of course this new generation’s first instinct is to go all in and then when a correction or crash sets in, they lose everything. They then go away and never come back. It’s a never-ending cycle.
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.
