I presume that "the last few days" takes your scalping trades to be somewhere between the 13 and 17th of this month, where the behaviour of your investment was in a clear ascend (https://coinmarketcap.com/currencies/dogecoin/). Now had you started on the 20th and tried the same until today, the result may well have been very different. Lucky strikes are something one can be glad about, but shifting the window of the timeframe a bit may render unforeseen results. That applies to bitcoin, dogecoin, or else.
