In my early days on trading and investment, I make series of mistakes and couldn't discover the difference between altcoins and bitcoin in cryptocurrency, then I continue to invest more on altcoins and before I know it, almost 70% of my portfolio goes for altcoins and bitcoin was not that really much, then I keep holding till I lost more than half of my assets before realizing what's at stake, now I've already made the decision right, the table is turned and I reverse the entire process as against how I was holding before, bitcoin is my major holding, I trade for a short time, buying the dip and holding, selling high and reinvesting when the market falls, I buy upon every dip, while my altcoins portfolios are for holding within a particular season they all perform well.
