Investing on alt coins is simply waste of time like if you want to hold the funds for long term investment. For short term for investment you can always choose the trading as your field and then you can go with it.
If there is any clumssy behavior in altcoin you can skip such altcoins and goes to other cryptos.
Everyone thoughts are different and indeed any investment this year will disappoint everyone. I think investing altcoins during this period will cause you to lose more money and the risk will increase if Bitcoin trends to drop in the bear market. Now all analysis is wrong and maybe this year we will face new difficulties so now is not the time for you to invest all your assets. Of course if you don't have too many financial problems then investing in this market will be a great opportunity for you next year.
All started last year not only this year but things being worst by this year . but yeah we should not focus on lost and think only possitive way whalving will happen next year and i believe this will be a big help for the price .
