Do you search for and look thru new cryptocurrencies of the day every day? The prices of newly launched currencies should have no choices other than rise to multiple times high. These currencies may not have long-term pontential. Invest 10k in such a currencies, dump them and make big money in short term.
There were altcoins which skyrocketted to 100 times higher in just days.
Very old altcoins may take very long time to achieve multiples. Even like eth, ltc. They wont go to 100 more expensive anymore. But very new cuŕrencies can.
I think top ten old altcoins have achieve saturation.
Is this your investment strategy?
I try to invest like this sometimes too, but it is highly risky. It just like take a huge gamble on weak football team, If you win, you'll big but you'll lose more often than you'll win. You can only try this strategy if you're sure about the prospects of the coin.
