Traiding is not that hard, but it takes time. Even if you buy at high price, just wait a month, two or half a year, price will go back and even above your buying price. Buy when it's falling, sell when it's rising.
and trading is not easy as you think, some times you buying at higher price then you panic and selling your altcoin/bitcoin
and some times you buying at failling ptice but the price will be failling more and more
But the price is also now rising so maybe next year you can sell it and the halving is also coming towards to us.
