To don't think that I am talking bullshit here. Some people they avoid to see the reality because it makes them feel bad.
Last April BAIKAL Batch 1 was out for $1200. Bitcoin price was 1BTC= $1175. So you spent 1.021 BTC to buy X10
In January 1 BTC was $20.000 (I don't think your X10 made you $18.800 profit )
Today 20 April 1BTC is $8.334 (Again your X10 didn't make you $7134 in profit )
So By don't buy BAIKAL and investing to BTC or altcoins you earn more.
In April 2017 you invest 1BTC and you payed $1175
In January 2018 you had $20.000
Today you have .............$8334
And if you bought X10 let's say you was lucky and you manage to make something but if you bought BAIKAL N,N+, B , Bitmain D3 , L3+ there you cry badly.
Think before you buy these ASIC miners and think how much will last this miner
