Why not do altcoins anymore? Because it's too exhausting. If you do altcoins, you must understand BTC. At least BTC cannot have a big dump. When BTC rises, altcoins may not necessarily rise. When BTC falls, altcoins perform a free fall. Those who make big money, like bit浪浪, mainly still play with BTC. The price rise of BTC is real and steady, climbing in pulses, while altcoins are not like that. Altcoins suddenly pump solely because there is no depth in the upper price range. You can make money off the depth difference, but you can also get trapped by it.
