I think it is achievable but ot will be very difficult in current market condition.Now it is bear market you have to be very cautious before investing in any coin.I would suggest you to invest in solid project which have a long term value.Never buy coin that are low in volume because it is very risky.
Pointed out. Gaining a 10% in a week for all trades is possible but difficult to achieve with our current market now. We are on a bear market right now where the prices are quite lower than it got highest this year, it is very risky to invest in a coin with a huge amount of money. I would suggest to not to be afraid, try some and invest some in modest amount so if tragic scenario comes it would be okay.
