I suggest you buy eth, dash and ltc not for doge. Eth is the best coin after btc ( depend on my opinion ), there's no doubt. If you have time just try look price action and volume this coin. After buy it just wait and see, reach your point take profit and enjoy. For dash and ltc, you can use 10% - 20% from your money to investment and don't sell it when weekend just sell it another day. Never forget stop loss and using only 40% for all coin you buy, it's secure. Trust me and good luck.
