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.
If we expect good things by investing in the wrong places, it will be like cleaning a mirror with dirt on our face. Investing in the wrong place means making a mistake in the beginning, and how can those who make such mistakes in the beginning expect anything good from the investment.
ALT coin is never a perfect coin to invest and I think it would be a wrong decision for an investor if he decides to hold the investment in such coin for a long time. If an investor is planning to invest and if his plan is long term then he should accept Bitcoin for investment without thinking anything. Bitcoin offers an investor as much financial security as any other coin in the market, but not as much. Holding the investment is the next thing but the first and foremost thing for an investor is to invest in the right coin.
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.
A long time ago I started my first investment and I have been able to hold my investment till now. The amount of investment that I started with in the beginning has increased today and my investment amount will increase more in the coming days which means that I can definitely hold my investment for a long time.
