If we all don't come together to buy bitcoin and not bullshit alt coins then none of these coins will exist soon

Not true. Bitcoin is a black hole for your money. There is no sense in buying it as it constantly looses value due to inflation. Litecoin is just worse that's why it even make less sense to buy right now.
We should all stop supporting inflationary currency at least until their inflation is smaller. Inflation doesn't make sense.
Buy bitcoin and litecoin not before year 2020 if you like profit.
