by the way, I am 28 yo I am not rich and I invested a lot of my savings, especially I bought a lot of LITECOIN....f**k 
Why Litecoin? You should have focused on Bitcoin, Litecoin is a clone with no added value to the original.
I bought before, but unexpectedly it continued to depreciate, I was reluctant to sell at a low price, now I have about 1000 litecoins.
You should sell your litecoins now it's actually overvalued at the moment. How much did you buy your ltcs at btw?
