Bitcoin is the forerunner of all cryptocurrency exchanges, which we can see that the whole world has seen the rise of cryptocurrency through Bitcoin. Simply put, Bitcoin reigns supreme when it comes to cryptocurrency discussions.
Based on the market performance we can say that investing in Bitcoin is a safe option, but the growth of Altcoins is fast and phenomenal. Besides Bitcoin we can dip other Altcoins because there are many Altcoins which have increased by almost 1000% in 4 months. With such gains comes risk although Altcoin dips will be riskier than Bitcoin dips.
We talking about real investment here in this space and not about gambling with money through altcoins as you suggested. True bitcoin has been phenomenal and has paved way for other cryptocurrencies to enter into the market but bitcoin is entirely different from altcoins. And every dip in bitcoin price is more like an opportunity for a DCA investors unlike altcoins where almost any dip can send those shitcoins to a journey of no return (dump). No experienced investor that want to invest long will buy the idea of investing in an altcoin except there's some sort of ignorance somewhere in the middle.
You're right @ letterhub, that statement could mislead newbies who are about to start their investment journey to deviate from the main point of focus into investing on shitcoins cause they'll feel that their are good alts that could make 1000% in the next bull run, most of these newbies are very naive and would jump into any opportunity they see in this space based on the information they get from older members so it's in our best interest to pass the right informations here based on those sets of people. Altcoins is not a good investment option due to the high risk factor involved in it, it's mostly for traders willing to take the risk and any experienced investors would teach people to prioritise buying Bitcoin and invest for a long time and use good methods like the DCA to help them on their investment journey. Bitcoin is superior to all others and still remains the best Cryptocurrency for investment regardless of how well several Altcoins have gained profits to people over the years.
