It's not enough having an investment plan, knowing the right choice to make for every investment defines the investor better. Take for example jumping on every new coin we find on reputable exchange might not be enough guarantee that coin will do well in the future.
It is advised that an investors should study the mrket of the new coin first, its fundamental and potential before jumping into investment. This is the basic of investment. If one just jump into new coins in the market, this investor might find himself losing money because he is just investing blindly. Not all new coins are successful many of these new coins failed, we can see it by looking at the list of new coins that failed during their exchange listing.
Some coin might have good Supply but low liquidity, some might have high market capitalisation but very poor volatility. Although it's hard to predict the accuracy of a coin performance in the near future this why it is always advised to stick to the known which is BTC.
There are also some altcoins that have good liquidity and has a potential greater than the current situation of Bitcoin to grow. So I suggest to have a diversion and search these potential coins that can exceed the current profit multiplier of Bitcoin.
