If look at this picture, it turns out that diversification is not such a good idea.
Diversification doesn't truly exist in a highly correlated market. The crypto space in one of such markets where currencies mirror the price actions of others, so when there is a crash, majority of coins get effected, similar to when there's a spike up.
A diversified portfolio would contain assets from different niches, real estate, crypto, stocks, gold etc.
Exactly, I don't understand why people say they diversified their portfolio when buying BTC, ETH, and LTC, If one goes up it's highly likely the others will too, if BTC drops for sure the others will take a dive too, so what's the diversification in it? It's like buying Shell and Chevron stocks or AMD and Intel and saying you're safe because your portfolio is diverse.
I really don't get why would someone choose to spread his money over multiple coins to avoid risks when obviously it's not going to do anything.
Looking at the presented table right now, I could note how XRP have fallen over the years and it's surprising its been a major competitor to ETH and now, its gradually falling off the top 10.
The only surprise is why that coin is still in the top ten as it offers nothing compared to other cryptocurrencies and their business plan of having something run on their private chain is really hard to understand, why would a private company run its private finances on somebody else's architecture when it could simply do its own centralized and far more secure solution?
Why would a bank use their chain and not create their own ?
