I believe the crypto market is here to stay. So no need to worry about the value of carefully selected tokens vaporising completely. Set aside an investment fund - whatever you have saved - that you do not need to have access to for the next 12 months. Do NOT borrow fiat to invest in crypto - the market is too volatile. As you have suggested build a diversified portfolio & HODL. You should be able to sleep well & probably experience outsized investment returns in the future. Do not let greed drive your investment decisions.
