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.
As long as there is a price movement, even though in a range that is not too wide, we can still benefit. 10% a week seems make sense. So, even though we are in a downward trend, but to get profit through trading is still widely open.
To even be able to get something like that, it all depends on your style of trading as well as the condition of the market. Usually for day traders, the chances of getting 10% weekly is possible, but at the same time, you also have to understand the risks involved when it comes to day trading as it is not always an easy thing and at the same time, nothing is always guaranteed.
To get something substantial most of the time, it is always very good to take advantage of a volatile market which is why you need knowledge and know the importance of stop loss as well. As long as you are able to inculcate all of that, you will always do great.
In this bearish situation it is not possible because the price is not increasing and when price is not increasing how is it possible to make 10% in a week? If you want to make big money from your coins, you should hold your coins for long time till the price cross atleast $8000. May at the end of this year this level be crossed by bitcoin but still there is no chance for that?
