150 ETH is much more risky, but you will have a bigger profit.
I think I will play safe so 9.5BTC and then trade to go to 10 and after HOLD
I also think that investing only in ETH is very risky. Now the price is low, but it is better to invest in both coins.
then it would be better to invest when the ethereum price is low, because this coin is still of great potential to rise again, and by buying it at a cheap price, we will get profit a lot
