What do you all think about a strategy of just investing a little bit in each of the top 100 coins, in hopes that one takes off? Seems like downside risk would be minimal.
Diversification is a way to minimize the risk by putting your money on different places. But make sure that you have a considerable amount on each instrument or coin. This is just to make sure that profit if ever there is enough to cover fees and other expenses incurred.
My opinion is that diversification is an additional risk. You knowingly invest money in coins that may lose their value. In a moment of crisis, the most persistent are the coins with the largest market capitalization. They have something to lose. Coins with little support will simply disappear. I keep my savings in bitcoin and Eth.
