yes crypto world is tough ... hard to grasp for a normal investor due to it being decentralized. The chances of small investor getting their investment burnt is very high as a result. Crypto world is full of tech bots trying to read market signal and thus triggering automatic buy/sell order based on market dynamics.

This also makes the entire space highly volatile, and one should not invest more than 10-20% of his total savings in crypto at least in my opinion, funds he/she will not be requiring for alteast a year.

Additionally, you are always in risk of losing funds as a result of hacked exchanges, which is becoming quite common, or end up losing your funds from private wallet being victimized of losing your private key to phishing sites.
