The best way to invest money is ICO, IDO and other presales. This way of investing is recommended even to newbies, if they invest in projects that have good fundamentals and a big number of partners and funds. Actually, it is difficult to be whitelisted and get an allocation so as to be able to buy tokens before their listing on an exchange, but if you devote to it enough time, you might get big profit.
ICO and IDO do not promise profit on every investment, usually the price will increase due to high demand and liquidity, but some things need to be researched before joining an IDO and ICO, because many scam ICOs end in Rugpull, always be careful in choosing projects so as not to lose when investing in any new project that is still under development.
