I've been looking to invest in some rising altcoins for quite a while now. Any suggestions for temporary investment? 
for now in the altcoin session there are plenty of good altcoins to invest in. because many altcoins are on the rise in the near future. You can notice BNB has reached $ 679 and ethereum has reached $ 3.5k and there are many other altcoins such as doge, xrp, ltc. but my advice to you to buy bnb because in the near future the price of bnb will reach $ 1k
BNB is a good coin to pick, the continuous burns will make the value even higher than the current and $1k later is possible.
Doge coin is a good coin too, but the price is already high, i don't know if it will be profitable if we enter to buy it now.
