Many investors including myself prefer to invest in altcoin because they are still very cheap and i can get many bags as i want, many investors are into altcoins because they have missed the bitcoin opportunity, now not everyone can afford a single bitcoin and they see opportunity in other coins
If we can invest in bitcoin and atlcoin why not. Every person must have a bad experience about what they never had before as a failure to invest into bitcoin and then he got a loss and do not want to invest into it again. But for me personally, both bitcoin and altcoin can both generate profits if we can find the right opportunity and determine the right time to buy and sell it.
basically investing in altcoin or bitcoin is an option when investing, and certainly provides experience to these investors. and so far after altcoin has been around for quite a long time, both bitcoin and altcoin have been integrated with each other in the market and i think they both meet the needs of the people out there
