So many crypto currencies are coming UP . They are much cheaper than Bitcoin for now. It is so hard to decide which to buy . Some are in good promos, to buy or invest to it while it is cheaper and sell when the price Will getting high. Is it a good idea to buy while we can not afford yet Bitcoin?
For me invest what you can afford to lose, and make a research first before investing to project even it was cheap and you didn't know what is the project all it was still useless and maybe your assets became nothing so better you have enough knowledge on it and you gather a lot of research before investing your money in this time you need to be wise for you to able to succeed.
It is good idea if you want to buy cheaper coins instead of bitcoin, but you should keep in mind that there are many scam coins in new ICOs and you should be careful about your investment. Bitcoin is no doubt very costly but it is also guaranteed and more reliable than any other coin in the world. You will lose your money only due to fall in the price.
