There's a risk involved in chasing altcoins' surges, especially meme coins that thrive on narratives of higher profit but higher risks. With this, you risk getting burned and wiping out your portfolio.
You are safer than relying on Bitcoin dominance, as it has consistently shown that patient holding can generate profits. Although the process may be slow, it is safe, and you are not putting your portfolio at risk. Those who moderate their greed go for Bitcoin's confidence.
Bitcoins are surely considered as a safest coin to invest but we also have few of the top alts which can secure our investment while give us better profits. I would prefer BNB and ETH. Few of these top coins have the potential but not all of those. There are a number of altcoins which can show huge potential but the changes of loss are much higher. The higher the risk, the higher are the rewards. Mostly new people will prefer investing a major chunk into these alts thinking there might be a sudden surge which will multiply their capitals eventually.
This mostly does not happen. These altcoins will follow bitcoin's footsteps and will only show us a sudden rise if we see the same with bitcoins. Investments in bitcoin will be much safer as they can't drop to a point where all our portfolio is worthless but with few alts, yes that is possible.
