I had bought some bitcoins in late December when price was around $10K. I had put all of it to trade on some altcoins to get good returns. Now, I'm all in on Bitcoin Gold, I bought it at $110 which is down to around $26. Shall I wait for another bubble to build up or sell what I'm remaining with ?
Do not rush. And do not panic. Market prices fluctuate. You have to wait for the market price to go up to sell it. Or you can make an investment. And the rest you do to trade.
If you cannot wait for more time then you can convert your money from bitcoin to Altcoin but dont even think of selling your coins. You will lose lot of money because you told that you have bought bitcoin at $10k and today the price is about $6300, it means that you will lose $3700 against each bitcoin which is very big amount. Dont be panic and wait for some more time.
