- Bitcoin: You can invest but i suggest you to wait and buy bitcoins when the price is really low, and sell them when the prices are back at its normal form.
- Litecoin: Litecoin is for me the sleeping gold. It has the potential to rise and double his price.
- Dogecoin: Dogecoin is a small coin, but if you invest a little amount of money and it rises at price you can make some money out of it.
- ETH: ETH will rise for sure. It is like the next bitcoin for 2018. Blockchain already added ETH support so you can buy there BTC and ETH fast and secure.
