Hello guys, having been here for a while now, I feel that having a higher percentage of your portfolio on bitcoin and maybe the rest 30 or 35% on already good and established altcoins like ETH, BCH, Stellar, brave. BNB, Vchain, etc, is a good way of staying away from useless projects. I have come to an understanding that running after new promising projects always leave you heartbroken in 97times, and running after IEO to quickly make up for past losses lead to more havoc on your fund. So stick to the safe zone.
Investing in a new project has no guarantee that you will earn a good return like what you mentioned above its better to invest in Bitcoin and other popular/trusted project in the market to avoid lossing so much money and gaining a high percentage in the future but not all investors will go to your idea because there certain people love to invest in a new project.
