well risk too big i think but sometimes when bull some coins is still low. maybe the timing needs here we know asic cheap now. we not much trust on this time if calculate wrong become bad.
Still less risky than buying an already very expensive mining gear at the peak of the bull market due to FOMO only for the coin prices, mining profitability and mining gear value to drop a few weeks later.
In 2018-2019, when mining was unprofitable or low-profit, miners knew which coins to mine and most miners chose Ethereum. Now no one knows which coin to choose, because all these shitcoins for mining on video cards do not inspire confidence.
