Good Bitcoin/memecoin book recoomendations?

I plan that when i will have my income that I will invest like 20% in “safe” stocks and 5% in risky stocks like crypto-currencies and memecoins that can go down but also can make massive profits. Do you have some re.ccomendations for good and helpful books about crypto-currencies and memecoins?

I just first want to really understand everything before I will invest in it and im not really familiar with the whole crypto currency thematics and stuff like daytrading.
