Hi,
I had purchased around $50 worth Etherium few months back.Now the Etherium price is very high.
I could make a profit of around $15... Is this the best time to sell.
Will long term investment be fruitful ?
Hehe.. $15.
Good job kid! No sarcasm, you are on your way to financial freedom. If you ask me keep on doing what you're doing and invest money into cryptocurrencies. When you grow older you will thank your younger self because you will have enough money to be set for life. Cryptocurrencies are still young. Only sell when you really need the money.
