Felt with them for 3 months built up a high 6 figure account and the advised me that they were going to pay me out, they said I had to pay tax and sent ma a wallet to pay into, when I did not receive any payout after few days I contacted the again and was told they gave me the wrong wallet and it had gone back into my account. I received a second wallet and paid the tax again and was told the payout would be done within 2 hours it never happened, when contacted I was told the broker fees had to be paid before transaction could be completed this was done and still no payout. My dealings were with David Kramer who was my broker and Michael Levine Head of Finance.. Levine will not return phone calls or answer emails and David Kramer has not returned calls. I also spoke with 3 different people who said they were from BlockChain. My advice to all is don’t deal with BuildSolid if you do you will be in the same situation as me at 3 months.
