If you were in my position, what would you do? Would you sell all of your ETH during the current bullish market? Or will you "hodl" and wait until it goes to $5k - $10k? Do you think ETH's current prices are sustainable? If not, why? Any suggestions, or recommendations will be greatly appreciated. Thanks.

Will sell it in part, I will enjoy the advantage of the current bullish market, selling 50% of the eth that I have is not sorry because I can increase hundreds of percent from previous estimates. 50% I will hold to see the development of eth in the future.
