It is difficult to see the development of altcoins because such assets are quite speculative and when people do not understand the market movement it will actually lead to losses. But if people want to invest in altcoins then they should be able to look at the top coinmarketcap which has much better potential, although the level of risk is also large when someone doesn't understand how to invest.
There are many people who still invest in altcoins and perhaps they understand the fundamental level that can generate profits in the short term. If you don't want to take big risks then bitcoin is the solution because even though this asset is speculative, they have a moment of recovery before reaching the next ATH. That's why people prefer to invest in bitcoin compared to altcoins because even though both have risks, they are very different.
If someone wants to invest in ALTs then he must pick top 10 to 15 alts listed on CMC and study them for investment. Right now there are around 10k crypto listed on CMC and not all of them are worthy for investment. Bitcoin must be the primary coin where majority of your funds should be going and spend only spend cash into alts or in other words as much as you can afford to lose. Don't go for alts that look attractive due to cheap price, think wisely before picking your alt.
