Some coins under the bull will grow so much that will make you rich.
I agree but isn't it bitcoin will grow first before any alts? 
. During the beginning of the bull, bitcoin will dominate all coins and will lead all coins to downfall. And bitcoin is too expensive investment. In stable growth.
Wait, bitcoin is expensive? I think not, this is why if you only have 20 dollars in your pocket you can own a bitcoin, but only in decimal form. And what will you do with this Satoshi now? We live in 2019, and Bitcoin is not supposed to make another challenge and a breakthrough. People stopped to take it as a miracle. Bitcoin needs investments.
