The most important thing to do if you're new to crypto is to ask these questions:
1. Does this coin solve a massive problem?
2. Is the team incredible?
3. Is there a decent following?
4. Has this coin been audited for security issues?
5. Was there a shady premine or other red flags?
Stick with these questions and DO NOT SELL your good coins.
Big banks, corporations, even governments are beginning to jump in to crypto.
Once that wave comes, you will be happy you held your coins.
I think crypto is really promising, especially for well-known companies, security crypto and blockchain still need to be upgraded, because this is a problem we often encounter, "Market Hacked" and "Coins stolen" are included in the extraordinary issue in crypto
