i want to ask,, Is good if i sell my btc and all in hold eth? give me advice
if you have ETH better hold as of now as its value started increasing. But its not adviced to sell bitcoin to purchase ETH and hold. BTC value is booming compared to ETH. You must be aware of it. If you still wish to buy ETH, sell half of the btc you hold and buy ETH. This would earn you more than profiting from one coin. All the best.
maybe he can stick with bitcoin only and not buy ethereum. but if he really wants to hold ethereum then he can buy ethereum while the price is still the low price. don't take too long to think because every time is a value for us and don't be late to buy. but I think it is better to stay with bitcoin because the profit will be bigger than ethereum.
