Although sometimes we will refer to the "investor", this will be done in the meaning of "trader" rather than "investor". The trader is the one who makes frequent currency trading during a day and benefits mainly from the small fluctuations in prices, while the investor is the one who buys a significant amount of a currency and waits for a long time to liquidate it at a much higher price and to obtain the respective profitability.
What we should do - due to the peculiarity of the market in which we are going to act - is to create a portfolio consisting of coins that will satisfy both versions of trading, since acquiring Bitcoin for trading is in itself a long-term investment. So, we are called to be both traders and investors.
