It is always wise to keep the investments in long term altcoins (BTC,ETH) .There are many other coins as well but it all depends on the market cap and their performances in the past. I still advise invest only what we can afford to loose , i would always invest 80% of the portfolio in major coins and rest of them in other altcoins based on the research and their market cap. Keep investing in good coins and reap profits.
I just want to build wealth and wanna multiply the same removing some profits as well which will help in survival. Still i would multiply as much as i can and buy some good coins like ETH , BTC and hold them to reap more profits .Thats the only goal i have as of now . I would advise other also to follow as building wealth is most important and to remain consistent as well.
I would suggest hold 50% of the coins and rest of them either you can sell to fiat or convert them to ETH or any other altcoins which are in their early stages. Even that would give u good benefits in terms of money and no of coins will also crease gradually. So its all upto you but still i would suggest sell the bitcoins not completely but partially and rest of them you have to take a call with the options given above.
Tokens drop as major of the crypto currencies are in rising mode , the other alt coins will only rise when we see some downfall in the major altcoins. Its not mandatory that this should happen, but this is the overall analysis what i see from the last few years. We will see much price action in all the altcoins in the future as many of the coins are coming with good concept and business model.Lets hope for the best.
