I am already bankrupted

Although there looks not much idea behind most coins, it looks like it is working

Usually you pay for services, goods. I don't know what happens now with most coins

Maybe just speculating is still be worth.
I think that BitCoin will hold his price longer than others and could increase to higher values as it is just money with a good name. I had good idea that it would increase when it was 10000 $, around last year october, however I could not step in.
Then why you are still searching for new altcoins to invest? No one can guarantee you that which new coin going to have success in future. Majority of new crypto ends badly. People invest in new coins to take the profit in short term. If you want to keep your investment safely then choose bitcoin or any other top good altcoins. Bitcoin will have more strong position and higher price after few years from now. Maybe it won't give you the high percentage of profit like your expectation (from new coins). But it will ensure you the profit.
