Biggest mistakes in crypto are

 *investing in projects which was not understood well
 *investing large portion of money in to low cap coins and meme coins
 *keep low cap coins and tokens as a large portion of the portfolio
 * not to have a portfolio
 * falling love with coins and tokens
 * influenced by twitter crypto influencers who get paid to promote hype currencies
