In as much as every investors is entitled to his decision on investment shouldn't give them the mindset of believing that altcoins is good for investment, come to even think of it which investors will clearly see how good, potential and profitable Bitcoin is and they would ignore it to go for altcoins which there potentials are unknown.
Sometimes most of the failure on investment is as a result of bad investment decisions because in times investment only profits making should not be considered perhaps aside from profits the legibility and potential should also be considered because is better making a little profits but consistently than making a huge profits at a time and lose everything tomorrow.
One thing I always don't understand is why some investors invest in other coins instead of Bitcoin. Where other coins in the market are directly dependent on Bitcoin, it makes no sense to keep Bitcoin and invest in other coins.
I have always put Bitcoin first in my long-term investment plan since the beginning.
Perhaps most investors are looking for an easy way they could invest and be making money on a regular basis, so however seeing Altcoins as the only alternative of reaching to there goals, and most of the investors normally prefers altcoins because they uses a strategy of following some crypto influencials to know when they would give a call to purchase a particular altcoins so that they could buy and sell immediately, which is a very bad investment plan because an investor could easily be cut off by the market price and lose almost everything.
I don't know why most investors seem not to be bothered about the likely challenges and the risk of putting there money on altcoins because the earlier they realize themselves the better for them because on a daily basis that's how most altcoins investors are becoming victims, because I even had the experience when I started investment, so I was encouraged by a friend to invest on altcoin and did, so up till now i have not realized my capital and the altcoin has been dumped, so that's were I learnt my lesson so I can never invest my money on altcoin.
