probably my last question. on ico platform it's written that balances are not updated automatically if investment is done in waves - are they updated manually sometime? made small investment as a test to check sometime ago but haven't seen any incent in numbers yet

Sold waves and then btc send to ico,this more simple,and my opinion.
this is not a good choise - you can get 5% bonus with waves investment and everything's fixed at a time of investment (see my previous questions). It's best to buy waves, increase price of waves, then do an investment. Just to be sure we are given a proper amount of incent I made a test investment to see how much tokens will be issued, but as long as this is not working automatically asked when it#s updated manually.
