I agree with you on this, altcoins are more profitable than bitcoin base on the fact that bitcoin doesn't move so fast like altcoins that can turn 100% within 24hrs
The opposite of this is also true and you should also show the other side of the picture. Just like altcoins can move up more quickly than bitcoins, the altcoins can dump very fast too and they can make your portfolio even zero. Bitcoin may not give you very quick profits but it is a safe investment when compare with most of the altcoins.
Altcoins is too risky as an investment for long term, when you invest on altcoins, you should not be greedy enough to hold longer, always find the best timing when you are satisfied and sold what you have and then reinvest when the price dump or reach again its dip, that's the lesson I learn from the last bull run and after the bull run when is the long correction period.
Altcoins may be too risky but if you study well about the possible outcomes you can earn really earn in the future. Investing is not easy because you are depositing your money in a project that is long term before you can earn. I can say that we should be patient and wait for the right time that the moment you waited happened. Cryptocurrency is volatile in terms of value that is why there is a big chance that the project you chose can pump up especially when bull run happens. You should also choose or pick a project that is promising and you can also get some information to the other investors or buyer on why are they investing on that particylar project. Gatherevery important information and grab the opportunity while the price is still low so that your money will be doubled in the future.
