I've been looking to invest in some rising altcoins for quite a while now. Any suggestions for temporary investment? 
There are so many altcoins prices that are low at bearable prices. Of course, Binance exchange listed altcoins. I really missed the Cartesi project, even this bounty campaign. I will suggest you two altcoins but those aren't Binance listed and good for temporary investment. Although I'm not forced to invest without your investment research, One is CTI and the second one is Radix. For every altcoin liquidity is important that it will be simple to buy and sell it. There are services like https://www.koinal.io/ that allow to buy and sell cryptocurrency directly from bank card.
Before investing it is necessary to check all details about altcoin. It is good that there are services that allow to buy cryptocurrency directly from bank card. I checked https://www.koinal.io/ site it allows to buy cryptocurrency by bank wire.
